Hello,
After a 7 or 8 year trial with Mac OS X, I'm back to Debian. I have one
of the first generation Mac Pros (model 1,1) and I'd like to keep OS X
in a dual-boot mode temporarily, to deal with opening the occasional
file that linux can't (such as Mac's Pages and Numbers files).
There are three 500 GB drives and one 1 TB drive. The configuration was
that the first 500 GB disk holds the OS, the two other 500 GB drives are
RAID 1 for all my data and work. The 1 TB disk was for Time Machine
(Mac's back-up program).
After backing up all my data, I moved all the files to the first 500 GB
drive and the two RAID drives are open. I also don't think I need to
keep the Time Machine backup, because all my work from now on will be
under Debian.
I have looked around for install reports and I know I have install rEFIt
(or the name is close) to get the dual boot working, but I'm still
uncertain about how to best organize things. Here are some of my questions:
- with three identical 500 GB drives, I think I could do RAID 5. I like
the security of RAID 1, but I think RAID 5 gives a performance boost
with a fair amount of security. Should I consider RAID 5? Under what
circumstances would it be advantageous? If I do this, I move the OS X
partition to the 1 TB drive for a while. But during the Squeeze install,
how do I specify RAID 5? I only saw reference to software RAID when disk
partitioning came up during the Debian installer.
- I have LVM on my laptop with Debian and it sounds like I'd want LVM on
the desktop too, to easily incorporate the former OS X drive down the
road. During the Debian install software RAID and LVM appear to be
different choices. Is RAID 1|5 compatible with LVM, or does one exclude
the other?
Suggestions, layout recommendations, pointers to reading are quite
welcome. I'm not really sure where to start with this part. Thank you
for your time.
