Hi all,

Many thanks for all the input, I did wait the 20 hours, but when it was 
finished, the performance was still slow. And trying out different options for 
the array didn't actually help.

Thanks to the thread "1-Terabyte drives - 4K sector sizes? -> bar performance 
so far" I figured out the problem (4KB sectors).
After changing the partitions to use sector 64 as start (as opposed to 63) a 
build of the array should only take 6 hours.
Hopefully, the raid-array will also show a better performance when this is 
finished.

I have similar disks in my new system and was lucky that I was still in the 
testing phase and hadn't filled the disks yet.
After changing the partitions to start at sector 64, the creation of the 
RAID-5 set went from around 22 hours to 9 hours.

I also get a much higher throughput (in the range of at least 4 times faster), 
so I would recommend doing the change if you can.

I now only need to figure out the best way to configure LVM over this to get 
the best performance from it. Does anyone know of a decent way of figuring 
this out?
I got 6 disks in Raid-5.

Thanks,

Not sure where LVM would fit into this, as then you'd need to offload the data 
from that PV (Physical Volume) to a different PV first.

With Raid (NOT striping) you can remove one disk, leaving the Raid-array in a 
reduced state. Then repartition the disk you removed, repartition and then re-
add the disk to the array.
Wait for the rebuild to complete and do the same with the next disk in the 
array.
Eg: (for a 3-disk raid5):
1) remove disk-1 from raid
2) repartition disk-1
3) add disk-1 as new disk to raid
4) wait for the synchronisation to finish
5) remove disk-2 from raid
6) repartition disk-2
7) add disk-2 as new disk to raid
8) wait for the synchronisation to finish
9) remove disk-3 from raid
10) repartition disk-3
11) add disk-3 as new disk to raid
12) wait for the synchronisation to finish

(These steps can easily be adapted for any size and type of raid, apart from 
striping/raid-0)

I do, however, see a potential problem, if you repartition starting from 
sector 64 instead of from sector 63, the disk has 1 sector less, which means 
4KB less in size.
The Raid-array may not accept the re-partitioned disk back into the array 
because it's not big enough for the array.

I had this issue with an older system once where I replaced a dead 80GB (Yes, 
I did say "old" :) ) with a new 80GB drive. This drive was actually a few KB 
smaller in size and the RAID would refuse to accept it.

Stroller, it is my understanding that you use hardware raid adapters?
If that is the case, then the mentioned method won't work for you and if your 
raid-adapters already align everything properly, then you shouldn't notice any 
problems with these drives.
It would, however, be interesting to know how hardware raid adapters handle 
these 4KB sector-sizes.

I believe Paul Hartman is, like me, using Linux Sofware raid (mdadm+kernel 
drivers).

In that case, you can do either of the following:
Put the whole disk into the RAID, eg:
mdadm --create --level=5 --devices=6 /dev/sd[abcdef]
Or, you create 1 or more partitions on the disk and use these, eg:
mdadm --create --level=5 --devices=6 /dev/sd[abcdef]1

To have linux auto-detect for raid devices work, as far as I know, the 
partitioning method is required.
For that, I created a single full-disk partition on my drives:
--
# fdisk -l -u /dev/sda

Disk /dev/sda: 1500.3 GB, 1500301910016 bytes
255 heads, 63 sectors/track, 182401 cylinders, total 2930277168 sectors
Units = sectors of 1 * 512 = 512 bytes
Disk identifier: 0xda7d8d6d

   Device Boot  Start End  Blocks   Id  System
/dev/sda1  64  2930277167  1465138552   fd  Linux raid autodetect
--

I, after reading this, redid the array with the partition starting at sector 
64. Paul was unfortunate to have already filled his disks before this thread 
appeared.

The downside is: you loose one sector, but the advantage is a much improved 
performance (Or more precisely, not incur the performance penalty from having 
misaligned partitions)

I actually agree, although I think the 'best' solution (untill someone comes 
up with an even better one, that is :) ) would be for the drive to actually be 
able to inform the OS (via S.M.A.R.T.?) that it has 4KB sectors.
If then fdisk-programs and RAID-cards (ok, new firmware) then uses this to 
come to sensible settings, that would then work.

If these RAID-cards then also pass on the correct settings for the raid-array 
for optimal performance (stripe-size => sector-size?) using the same method, 
then everyone would end up with better performance.

Now, if anyone has any idea on how to get this idea implemented by the 
hardware vendors, then I'm quite certain the different tools can be modified 
to take this information into account?

And Mark, it's not just people installing binary distros, I think it's 
generally people who don't fully understand the way harddrives work on a 
physical level. I consider myself lucky to have worked with older computers 
where this information was actually necessary to even get the BIOS to 
recognize the harddrive.

Don't get me started on those ;)
The reason I use Linux Software Raid is because:

2) It's generally faster then hardware fakeraid

That doesn't mean a thing, I'm afraid.
I have the 4KB drives (product-code and behaviour match) and parted also 
claims my drives have a 512B logical/physical sector size.

I've been using LVM for quite a while now and prefer it over any existing 
partitioning method. Especially as this array is for filesharing and I prefer 
to keep different shares on different partitions and the requirements for 
sizes are not known at the beginning.

Also, the machine this is in uses Xen virtualisation to consolidate different 
servers on a single machine (power-consumption and most servers only need a 
lot of resources occasionally) and I already have over 80 LVs just for the 
virtual machines themselves. (multiple each, as I don't like a single large 
partition for any machine)

As for recovery, I always use "sysrescuecd" (http://www.sysresccd.org) and 
this has Raid and LVM support in it. (Same with the Gentoo-livecds)

I completely agree with this.
RAID is for redundancy (Loose a disk, and the system will keep running)
LVM is for flexibility (Resizing/moving partitions using parted or similar 
takes time during which the whole system is unusable)

With LVM, I can resize a partition while it is actually in use (eg. write-
activities)

I don't consider that comment as "snobbish" as I actually agree.
But as I am using 6 disks in the array, a hardware RAID card to handle that 
would have pushed me above budget.
It is planned for a future upgrade (along with additional disks), but that 
will have to wait till after another few expenses.

My mainboard has PCI, PCI-X and PCI-e (1x and 16x), which connector-type would 
be best suited?
Also, I believe a PCI-e 8x card would work in a PCI-e 16x slot, but does this 
work with all mainboards/cards? Or are some more picky about this?

The mainboard I use (ASUS M3N-WS) has a working hotswap support (Yes, I tested 
this) using hotswap drive bays.
Take a disk out, Linux actually sees it being removed prior to writing to it 
and when I stick it back in, it gets a new device assigned.

On a different machine, where I tried it, the whole machine locked up when I 
removed the disk (And SATA is supposed to be hotswappable by design...)

Not sure where the kernel-image is on the CD, but have a look in the ISOLINUX

As for the ".config", I think the kernels used by Gentoo all have the

Eg. to get the config, do the following:
zcat /proc/config.gz > .config

It's what all the buzz says, but I've yet to have that confirmed. It's

Yes, but just for cloning, wouldn't it be just as easy to power down the 
machine, plug in the drive and then power it back up?
Or even stick it on a quick-change USB-case? :)

I do have to say here that the mainboard for that machine is now easily 5 
years old, so I didn't actually expect it to work.

I think it depends on if the controller actually sends the correct signals to 
the OS as I'm not sure if it was Linux or the hardware locking up.

Hi Colleen,

I also have one of those All-In-One printers.
To get it to work, I added the "saned" user to the following groups:
- lp
- usb

I'm not sure, but I think "usb" is sufficient for the scanner, but with these, 
it works on my system.

Because on flash-drives (Which are used in small devices and netbooks) you

And with minimal memory, I don't want to have a ram-disk gobbling up the

A simple message passed to apps which are listening is much better. It's 
short-lived and only uses (minimal) resources when the message is broadcast. 
After that, it doesn't linger, unless I am running an app that stores these 
messages somewhere. (Probably a debugger)

Netbook: 1GB of ram, with Linux, I can easily run all the software I want , 
without need of any swap.
Can I do the same with 9P? Eg. will I be able to run all the software I use on 
my netbook without having to spent time on porting it all?
Is also all the hardware supported in 9P? Linux supports all the hardware in 
my netbook.

Unless the answer to this is a 100% yes, 9P is never going to be an option.

I use Gallery myself for my picture collection and this can be configured 
easily.
As in, you can allow users access to all versions or just the 'resized' 
versions.
This can be done through groups or specific users.

I usually only allow people to access the resized versions. It does support 
resizing on-the-fly, but only to the sizes you actually configured for that 
particular photo/album/...

the on-the-fly bit is only done if the requested size doesn't exist yet, eg. 
it will only do it once (unless you clear the derivatives folder ;) )

As your root-filesystem does appear to be mounted, can you give use the result 
of the "mount" command to see how it identifies the root-filesystem?

I have seen harddrive naming schemes change between kernel versions. Eg. hda 
might end up being hdb or hdc,... (same with sd.)

Alternatively, to avoid this, you could use drive-labels and configure 
/etc/fstab with these labels rather then the drive-items.

Can you also show us the dmesg-output to see if the drives are actually 
identified?
If "udev" is not running correctly, the device-nodes might not be created 
automatically.

From this, it looks like the "syscon9" file is not in the ".../ccd/"

Also, isn't this file supposed to be on the server?

This seems to indicate it can't actually find the file 
"/etc/openvpn/ccd/syscon9"

This file needs to be located on the server, not on the client, as it's the 
server that determines the IP-address for the client.

This is the generally recommended method and I found this method in the Gentoo

be in the docs for long.

I have /boot mirrored, not actually tested with removing a disk yet, but I am

If not, I have other methods of booting the system and getting to the data.

Not necessarily, it might have a limited NAT-table per host, rather then a

The NAT-table is automatically filled with all the running connections to the 
outside world.
This table is how the router keeps track of which packets need to be forwarded 
to which machine behind the NAT-router.
Not all routers clear the cache quickly enough and most have a tendency to get 
filled with these.

It's exactly because of this that I refuse to use a "plug-n-pray" router and 
use a Linux box for this purpose.

I would still try Stroller's suggestion and turn the router off and on (But 
leave your computer running). It will only affect the connection briefly and if 
it resolves the issue, it will then be clear the problem is the router.
If the problem then still exists, the issue is somewhere else and we can try 
to find it.

Hi Petric,

I am not certain about git, but for subversion I had to set it in the 
subversion config.
On my system:
*
host ~ # cat ~/.subversion/servers | grep proxy
http-proxy-host = proxy.mydomain.com
http-proxy-port = 8080
*

I am guessing that a similar setting is required for git and others.

Wonko,

If your graphics card uses up the rest of the memory, moving up to 64bit won't 
help either.

Check in your BIOS to see if you can reduce the amount your graphics card 
uses. For 'normal' desktop use, around 64MB should be more then sufficient and 
if you have 4GB physically in your system you should then see more memory 
appear.

Depends on what you want to achieve. If you have only one screen and/or one 
machine with a decent graphics card then it does make sense.
However, X is a very inefficient protocol. Eg. it can clog the network.

Maybe, but VNC puts the remote screen in a window.

Yes :)

I use X-tunneling with ssh.
To get this to work, start with trying the following:

(machineA has screen, machineB is screenless)
on machineA # ssh -Y machineB
then, on machineB, start the program you want displaying on machineA, for 
instance firefox.

This is both easier to implement and also removes the security issues as ssh 
is encrypted.

The SSH-server needs to support it.
If the SSH-server does not have this option enabled (in the sshd_config), the 
"-Y" flag does not work when connecting to that server.

If you set the flag in the client-configuration (ssh_config, note, no 'D') then 
it will add the '-Y' option by default to all outgoing ssh-connection 
attempts.

Hope this makes sense?

I actually hit this myself yesterday.
When emerging "libpng", it mentions a script that needs to be run. I would 
suggest running that script.

I think the following commands were the ones that led to a properly upgraded 
system. It is now working for me, but it did take quite a while.
**
emerge -vauD --newuse world
lafilefixer --justfixit
/usr/sbin/libpng-1.4.x-update.sh 
emerge -vauD --newuse world
revdep-rebuild -- -va
emerge -vauD --newuse world
**

Alternatively, you could always try to one that should always work:

emerge -vae world
(NOTE: This will rebuild _everything_)

Btw, if you are using KDE, you might, like me, also hit issues with akonadi 
not starting (I couldn't not use it anymore)
Post on the list if you hit it, I still have these fresh in my mind :)

Not sure, guess I stopped reading too soon as I managed to get it to appear to

Anyway, am currently doing a " emerge -vae world " as I want to get it all

I have attached the output of "postconf -n" and the main.cf and master.cf 
files.
Don't have a ldap.cf file as it's configured inside the main.cf file.

The aliases are parsed correctly, but I noticed, while researching this, that 
it doesn't seem to correctly match the users, but relies on cyrus to tell it 
if the mailbox exists or not.

And before I forget, I use fetchmail to collect the email from my ISP and 
configured fetchmail to hand it over to postfix.

In addition to the screenshot, using Linux it's very easy to create an ISO-file 
from an existing CD/DVD.
I always do it with:
# cp /dev/cdrom /bladiebla.iso
(change paths / names as appropriate)

No need to install additional software to do this and I have succesfully used 
this to create ISO images from MS Windows install media as well for use with 
both VirtualBox and VMWare.

This is an easy way to install software that, when unpacked, is larger then a 
DVD, but don't want to copy it to the local drive every time.
I have a few ISO-images of around 14Gig with software on it. Just connect that 
to the virtual machine and install from there. :)

Most Dell-laptops actually work quite nicely with Linux, however, be aware 
that DELL has issues with the harddrives they supply.
I've seen 6 different recent DELL-laptops with crashed harddrives in the past 
1.5 years. These laptops were handled carefully.

Response from Dell was: "Sorry, we shipped a wrong batch"

I would suggest frequent backups of important files and/or the harddrive 
swapped for a more reliable model.

In this case they were Seagates, but as mentioned, all manufacturers make 
mistakes.
The last Dell that had a crashed harddrive (after 3 months of use, 2 weeks 
ago) had a Seagate - ST9160823ASG.

These were for a business customer (A big one) and all Dell offered was 
sending replacement drives to the seperate users' homes or their nearest 
offices.

Getting into the preferences of brands here, so I will refrain from

One thing to still keep in mind, Asus does not really care about Linux users 
either. Is there a decent laptop-brand that actually does?

Hi Felix,

Apart from what was already mentioned, you might want to also consider the 
following:

1) Even though people tend to try to do it correctly, non-natives can still 
make mistakes with the names. These mistakes are frowned upon by the natives, 
but are a part of live.

2) Names of cities can change with time, example:
"New York" used to be called "Nieuw Amsterdam" (Or "New Amsterdam" in english)

3) Some cities have multiple valid spellings in the same language:
The Hague = "Den Haag" or " 's Gravenhage" (yes, the apostrofe before the "s" 
is part of the second version of the name)

An easier option might be to filter on the post-codes, these should be unique 
and if you put the countries international abreviation in front of it, like 
so: "NL-1234 AA" or "D-12345", you have a single field to check and then link 
the actual city-name to the postcode area.

Disclaimer: I have no clue if these 2 postcodes actually exist

[gentoo-user] Raid 5 creation is slow - Can this be done quicker?

[J. Roeleveld]

Hi All,

I am currently installing a new server and am using Linux software raid to 
merge 6 * 1.5TB drives in a RAID5 configuration.

Creating the RAID5 takes over 20 hours (according to " cat /proc/mdstat ")

Is there a way that will speed this up? The drives are new, but contain random 
data left over from some speed and reliability tests I did. I don't care about 
keeping the current 'data', as long as when the array is reliable later.

Can I use the " --assume-clean " option with mdadm and then expect it to keep 
working, even through reboots?
Or is this a really bad idea?

Many thanks,

Joost Roeleveld

I did find the same results on Google, but not really a proper explanation as 
to why it's a "bad idea". Unfortunately, my budget doesn't extend to a 
hardware raid solution. (The cheap cards offload it to the CPU anyway and are 
generally considered slower in various benchmarks)

True, but I already ran "badblocks" twice on each disk to verify that the 
disks are fine. (No badblocks found).

Good point, and I agree, which is why I will let it finish it's course, but I 
also expected it could be done quicker.

I'm hoping someone with more knowledge about RAID-systems can throw in his/her 
2cents.

Hi,

Not sure if this will help, but when I was living in the UK, I used "adsl24" 
for my internet connection. Before that, I used ntl (taken over by virgin...)

I have always been using my own SMTP server, using the ISP-SMTP server as the 
relay-host.

Not sure if virgin changed the settings after taking over NTL, but with them, 
my 'from' address was never changed. Would be difficult as I would not actually 
log-in to their SMTP server.
Maybe setting up your local SMTP-server using the virgin one as a relay might 
solve your issue?

FYI: I use postfix for this and have the following in the "main.cf" file:
--
relayhost = []
--

Hope this helps,

Joost

PS. I am not in any way affiliated with adsl24, but they are quite cheap and 
are 
clued up about Linux

Take the following with the usual grain of salt.
I don't use WPA myself, but I have seen issues with WEP-passwords where not 
all systems convert it to the hash-value in the same way.

Try using the HEX-value for the WPA password rather then the "plain-text" 
version.

Thanks,

Just an idea, not tested:

Is there another "libcups.so" file somewhere?
If yes, create a wrapper-script that puts the location of the other 
"libcups.so" file first in the search list for the LDPATH-variable.

I believe you are maybe mixing up 2 things.
A SMTP-server accepts emails on port 25 and sends it on to another server, 
either another SMTP server or a mail-store (for instance cyrus or dovecot)

I don't think ssmtp actually listens on port 25, but only sends email to a 
SMTP server that does listen on port 25. (ports can be configured, but 25 is 
the default SMTP-port)

I actually use something similar:
ssmtp on the servers
postfix on my mail server

ssmtp is configured to pass all email to the postfix server on my mail server.
postfix is configured to either pass email on to my ISP (for outgoing email) or 
pass it to cyrus to store it on the mail server to allow my mail client to 
access it via IMAP. (POP3 is also possible, but disabled on my system)

In other words, you need  something like exim/sendmail/postfix/... on 'baby' to 
receive and store the email.
The other machines only need something like "ssmtp" to send email to 'baby'.

You could try setting up and configuring ssmtp on your laptop.
But as soon as you login to an SMTP server, the SMTP server knows which email 
to paste in

I actually use VPN to connect to my mail server at home. (never trust the ISP 
ones)

[gentoo-user] How to have init-scripts 'wait' for other servers

[J. Roeleveld]

Hi all,

Does anyone know if an existing method to have init-scripts on server A wait 
for a service on server B to be started?

Reason for this:
I have one server containing all the databases, one that operates as a NAS and 
the DNS is running on server 3.
In order for the different machines to start correctly, I need to configure it 
that server 3 starts the DNS before the other machines try to access other 
machines (don't want to maintain hosts-files as it all works fine once the 
servers are up and running)

Also need to make sure the database and NAS is running before the webserver 
starts.

I tried to google for it, but I can't find a usefull search string that will 
give me anything usefull.

I don't mind reqriting init-scripts for this, but am looking for a way to 
check if services are up and running from within the init-scripts.

Thanks,

Joost Roeleveld

I have been thinking of something similar, but before starting to write this 
myself, I wanted to double check if anyone has a better idea and/or already 
knows of a set of scripts/tools that already implement this.

Or, obviously, fails if it doesn't come up within a certain (configurable) 
time.

If there is no existing set of scripts, I will share whatever I come up with.

I will have a look at this. From the website it looks like it should be able 
to do most of what I need.
Might need to reconfigure a few things (like not starting all services using 
the 'normal' method, but I can live with that as long as monit can still tell 
me what is running and what isn't...

(added bonus, it's in portage: app-admin/monit )

Can you paste the exact output you get when you run:

# emerge -va --update --deep world
the "-va" will make the output verbose and will ask for confirmation if all 
dependencies can be resolved correctly.
(might be usefull to always use that to double check what you are installing)

[gentoo-user] Catch all mailbox

[J. Roeleveld]

Hi All,

I know this is probably off-topic, but I'm hopefull someone on this list knows 
how to do this.

My current situation:
Postfix gets an email delivered for user X
Postfix passes this to cyrus (lmtp-transport)
if user X does not exist within cyrus, the email gets bounced.

I would like this bounced email to be delivered to a seperate cyrus email 
folder.

I tried to find the answer on google, but all the solutions I found either only 
work with the postfix local delivery agent (eg. not compatible with cyrus) or 
requires a list to be maintained using all the known email-boxes.

I prefer a fall-back solution where an email directed at a user not listed in 
either the alias table (stored in ldap) or not known to cyrus is redirected to 
a specific cyrus mailbox.

Many thanks,

Joost Roeleveld

This does not work, "luser_relay" only works with the "local" delivery agent.
When using Cyrus, this has been changed to the cyrus lmtp delivery agent.

I did notice this option, but it would require me to duplicate the alias table 
into a alias file. I tried setting a "@" entry in my ldap-tree, but 
this did not work.

I tried this, but when looking at the ldap logs, I notice that the 'domain' 
part does not exist in the search string.
Eg. '%s' only shows the user, '%d' is empty, eg. query is ignored

Does anyone know how I can force postfix to add the domain to the search query?

Yes, I believe this is necessary for postfix to actually accept emails?

Or how else do I get this configured?

Today succesfully installed kde4.2 on amd64.
I first removed my old KDE completely and then installed it on a clean system.

Only reinstalling the old kde libs for programs that have not yet been ported 
to kde4.2.

Not run into any problems so far. Did have to unmask (~amd64) quite a few 
packages to get it to install.

I enjoyed MS Dos, then played a bit with MS Win3.11, MS Win95 and MS Win98SE.
However, for important stuff, like day-to-day desktop, I switched to Linux
in 1997. That was the last time I lost files due to a crash of MS

Not sure about availability, but Draytek has some nice routers with

You should've tried installing MS Office back then...
45 (Or there-abouts) floppies and the installer asking for them in a

The guy asking for it paid a lot for it, so it wasn't too bad. ;)

Pandu,

I haven't checked the source yet, but I'm wondering if the scripts are
looking for the "conf.d" file in the location:
" ../conf.d " (based from the actual location of the init-script)

Can you try the following:
# mkdir -p /opt/wallmator/initscripts/conf.d
# ln -s /etc/init.d/gatewall /opt/wallmator/initscripts/conf.d/gatewall

and then recreate the original link for the init-script.

How did you get  the server there? Flown it in?
I've seen the roads in Africa and those are difficult to navigate...

That's why I like the "ADMINISABSENTMINDED" option in the Shorewall
config. It doesn't kill existing connections.

I always test a new remote connection prior to closing the one I used to
change it with.
If I do accidentally kill my existing connection, the "safe_restart"
option will cause it to roll-back if I don't accept the new settings
before a time-out.

Stefan,

I haven't had problems with upgrading, but I didn't "wait" this long.
Eg. I didn't migrate from 2.1 to 2.4 directly.

I would suggest you check on the cyrus-imap mailing list (see bottom of
email) for tips. Installing it is simple, but there are a few changes with
some of the files.

A safer method would be running the 2 versions in parallel and using
imapsync or something similar to copy the email over to the new version.

What you're missing here is the fact that different tools report the sizes
differently.
Look into the difference between "GiB" and "GB":

http://en.wikipedia.org/wiki/Mebibyte

you have:
750156.38 MiB =
750156380 KiB =
75015638 B =
732574589.8 KB =
715404.87 MB =
698.63 GB

(with the "i" the factor is 1000, without it, the factor is 1024)

There is an example for this on the project homepage:

If you want to still try to copy the mail over, you need to look into

Wouldn't a good solution be to have the ebuild modified to only install

I had it working a long time ago, but the last time I tried it I ended up
with a bit of a problem:

I don't want a swap-partition on the SSD in my netbook. So I want it to
use the SD-card that's permanently plugged in. Problem is, it's connected
via an internal USB-port and USB is killed before the writing-proces for
the suspend-to-disk starts.

Anyone know a solution short of rewriting the kernel? ;)

True, but I don't want to have too many write-actions to the internal SSD,
which means that I'd want the file on the SD as well...

I'm not saying it is or isn't.

I just don't understand why "not upgrading for a while" is given as an
option considering the issues people will encounter when they try
upgrading a Gentoo installation that hasn't been updated in a long time.

Be careful here, not all SATA-controllers/ports on mainboards are hotplug
capable. I have a mainboard that becomes really unstable when I try to
hot(un)plug a harddisk.
It runs perfectly fine as long as I switch the computer off before

If the manual says it is, then probably it will be.

I have 2 mainboards I tried it with that don't mention either way for
hotswap in the manuals.
One gets unstable, the other works perfectly.

The last mainboard I bought actually has an option in the BIOS where I can
specify per SATA-port which are to support hotswap or not ;)

I don't have much experience with Hardenened, but are you certain that any
permissions (including ACLs) are set correctly for PostgreSQL to access
all its files?

Do you have "sec-policy/selinux-postgresql" installed? And did you
re-emerge this after the update?

If VPN is the only traffic to/from your home, eg. using your internet
connection and you control the VPN-server on the other side, you could
limit the "upstream" of the remote server to your home.

Are you sure those are all unique files?
Not multiple versions of the same movie? ;)

I've got a decent sized storage box as well. When building it, I already
planned ahead to allow additional disks to be easily added.
Now I need to change the layout at home, as she finds the server too noisy ;)

Before playing around with the kernel config further, I don't use
XenServer, but use the xen-stuff in portage instead. (My host runs Gentoo
as well)
In the configuration, I add the following to the kernel-parameters:
" xencons=tty "
Maybe a similar option will help you as well.

Otherwise, you could try checking the input-devices. Especially things
like keyboard/usb/hid/ps/...

Also, if you have further difficulty, the xen-users list might be a better
port of call as there are plenty of people there who use XenServer.

Hmm... I don't use kernel-modules in my Xen domu's (All are PV). I wonder
if compiling them into the kernel might help.
Or, try loading the modules listed above and see if that helps. (Not sure
if you can see an immediate change though)

I have attached the .config for one of my domains. It also has support for
a passed-through sound-card. You won't need that part. :)

Please note, I do use the following kernel:
sys-kernel/xen-sources-2.6.34-r4

Which kernel are you using?

Hmm.. Ok, my mistake.
I now remember I set it to tty to solve the issue I wasn't seeing any

Can you add a list of the ones you are missing?

My guess is, because you're not having the xen-patchset in the kernel.
Can you try the xen-sources to see if that helps?
Then we can work our way through the missing options.

Ok, then we'll need to look into things that are not added at all.

The following might be the one you're missing:
CONFIG_XEN_KEYBOARD=y

It is in my config, but not in yours.

Could have a few reasons:
- I have the "compatibility" for xen reduced to 3.4 or higher. Not sure
which xen-version is included in yours.
- I do not have support for an initramfs or similar in there
- I specified the CPU-type in the kernel (It's not a generic one)

Did you check the logs for xend, system (messages) and others?

I quickly checked, this one depends on the following additional option
which you do not (yet) have:
CONFIG_XEN_FRAMEBUFFER=y

If you disable modules-support, you should not require an initramfs.
Simply ignore that part and remove any reference to it from the config.

There are always things that can go wrong and I agree, adding additional
layers can increase the risk.
However, the benefits of easily and quickly changing the size of
partitions and creating snapshots for the use of backups are a big enough
benefit to off-set the risk.

Bind-mounting is ok, if you use a single filesystem for everything. I have
partitions that are filled with thousands of small files and partitions
filled with files are are, on average, at 1GB in size.
I haven't found a filesystem yet that successfully handles both of these
with identical performance.
When I first tested performance I found that a simple "ls" in a partition
would appear to just hang. This caused performance issues with my
IMAP-server.
I switched to a filesystem that better handles large amounts of small
files and performance increased significantly.

The way I do backups is that I stop the services, create snapshots and
then restart the services.
I then have plenty of time to backup the snapshot.
If I were to do this differently, I'd end up having a downtime for over an
hour just for a backup.
Now, it's barely a minute of downtime.

That, to me, is a very big bonus.

Unless I am mistaken, LVM does not provide redundancy. It provides
disk-spanning (JBOD) and basic striping (RAID-0).

For redundancy, I would use a proper RAID (either hardware or software).
On top of this, you can then decide to have a single filesystem, LVM or
even partition this.

I think the confusion might have come from the fact that both LVM and
Linux Software Raid use the "Device Mapper" interface in the kernel config
and they are in the same part.

Also, part of the problem is that striping is also called RAID-0. That, to
people who don't fully understand it yet, makes it sound like it is a
RAID.
It actually isn't as it doesn't provide any redundancy.

I do hope you didn't loose too much important data when you had this issue.

Naming part, there are 2 ways of finding it.
1: /dev//
2: /dev/mapper/-

You included a "-" in your VG-name, this is replaced with "--" under
/dev/mapper/

Looks fine so far, don't forget to put a filesystem on "/dev/sdb-vg/test"
to be able to mount it somewhere :)

Is the filesystem mounted when it tries to find the firmware?
In other words, are you perhaps using a ramdisk?

If you have this drives as a module, can you try removing it (rmmod
 and then reloading it (modprobe )?

If it isn't a module, can you rebuild your kernel to have the relevant
driver as a module?

6 months might not be enough, there was a thread called "[gentoo-user] A
tiny titillating taste of grub2" and dates back to 9 January 2011.

There also was a thread called "[gentoo-user] [cookbook] grub2 for idiots
like me" by walt (24 January 2011) which is, I believe, what you're
looking for.

You're welcome, my Gentoo-user archive goes back to 2004 :)

For correctness, please change the 4th line above from:
" modprobe -r foo bar && "
to:
" modprobe -r broadcom tg3 && "

I somehow doubt there will be a module called "foo" or "bar" :)

Hi Colleen,

I didn't find it in this thread yet, but I am wondering if you have the
CD-drive connected to the soundcard or not.

Some applications will "rip" and play the cdda-tracks directly from the
CD. Others will simply tell the CD-drive to play an audio-cd and have the
cd-drive do the decoding.
In the latter case, the audio-signal goes over a little cable from the
cd-drive to the soundcard.

Which Linux distribution are you using?
Gentoo does not use those files.

Try editing the /etc/conf.d/net file to match your network settings.
