I am about to do the same thing (3x = 3 independent GigE-connected
servers, each with their own 1TB disk-arrays and attached LTO
tape-bacukup units.). We have talked over the same issue, and have
chosen to use Reiserfs.
The debate continues about which is faster, more robust, lower CPU
usage, etc. but I think either XFS or ReiserFS is an excellent choice.
For me, ReiserFS won out for two practical reasons:
-we're using a lot of RedHat, and ReiserFS is basically included 'out
of the box'. During a fresh install, I use the GUI tool 'anaconda',
then Ctrl-Shift-F2 to a shell at the disk-partitioning point. Then I
use the miniroot tools included with RH to create the Reiser partitions,
and format them. Ctrl-Shift-F7 back to the GUI, and Disk Druid
recognizes the Reiser-partitions. Continue installation per normal.
You cannot use the GUI anaconda to create Reiser partitions, although it
will happily recognize them.
-our servers will be backed up by 'amanda'. You need special XFS tools
(xfsdump is one) that you have to Google for... It's just a slightly
higher hassle-factor, which I feel will complicate upgrades or
bare-metal disaster recovery.
Both are reputed to be very quick, support ACL's, handle large files,
Our servers will have these arrays configured to be one single
file-system (/home), with the Operating System to be held on RAID 1
(mirrored) smaller drives (this is purely to help cope with 1 drive
dying :-( ).
That's my $0.02 ;-) There may be all sorts of glitches along the way,
because I haven't yet actually done this installation yet. But I have
used the various components (including Samba 3.0alpha) for 8 - 20
