I certainly don't want to start any flame wars about choosing between 
ext3 of XFS.
One reason I was thinking of using XFS was because recently when I set 
up an ext3 system, during the setup a note popped up that an fsck would 
be forced on the file system after 180 days. Having to take down a 
crucial resource for a long period to do an fsck on 2TB of ext3 file 
system every 1/2 year is certainly unattractive! I know there are ways 
to change this default using tune2fs but I am uncertain what the 
implications of doing so are.
My previous experience with AFS file servers has been with AIX3.x - 
AIX4.x and Solaris 9 and I essentially turned the systems on and left 
them alone for years (literally - they went down whenever the building 
power failed for some reason or other). I am hoping that XFS would have 
similar characteristics.
