So far, so good. > LVM will provide me a way to expand storage with extra disks, but if > there is no more room for that kind of expansion, I was thinking of > GlusterFS for scaling-out. Let me suggest a different approach. It sounds like you're planning on a lot of future expansion. Get a high-end SAS RAID card. One with two external SFF8088 connectors. When you start running out of places to put disks, buy external chassis that take SFF8088 and have daisy-chaining ports. 2U boxes often hold 12 3.5" disks. You can put cheap SATA disks in, instead of expensive SAS disks. The performance may not be as good, but I suspect you are looking at sheer capacity rather than IOPS. Now, the next thing: I know it's tempting to make a single filesystem over all these disks. Don't. The fsck times will be horrendous. Make filesystems which are the size you need, plus a little extra. It's rare to actually need a single gigantic fs. > OS I would use is Wheezy.

Since 1997 or so, you have had the ability to upgrade from major version n to version n+1 without reinstalling. You won't need to reinstall unless you change architectures (i.e. from x86_32 to x86_64). -dsr- -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
