We've used XFS in some of the servers where we needed to implement
quotas. I was really dissappointed to see that XFS was not as stable as
we wished. The problems we had was also related with hardware problems
like disk failure. xfs_repair/check utilities did not work. It was a
filesystem corruption.
Now we moved these servers to ext3 filesystem and we did not met any
serious problems. The quotas seem to be working well.
I also have a question; (We had these kind of problems while we have
been using XFS, and we still have)
Quota for some users shows much greater than the size of the files they
owned on the filesystem. For example ;
[root@mail root]# mount
/dev/sda1 on / type ext3 (rw)
none on /proc type proc (rw)
usbdevfs on /proc/bus/usb type usbdevfs (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
none on /dev/shm type tmpfs (rw)
/dev/sdb1 on /var/spool/mail type ext3 (rw,usrquota)
[root@mail root]# quota -u XXX
Disk quotas for user XXX (uid 20561):
Filesystem blocks quota limit grace files quota limit
grace
/dev/sdb1 10276 20000 22000 1 5 10
[root@mail root]# find /var/spool/mail/ -user XXX
/var/spool/mail/XXX
[root@mail root]# ls -lh /var/spool/mail/XXX
-rw------- 1 XXX users 32k Mar 28 09:52 /var/spool/mail/XXX
[root@mail root]#
What may cause this? And what may be the solution ?
System Specs
OS : RH 7.3
Kernel : 2.4.18-26.7.xsmp
Filesystem Size (/dev/sdb1) : 106 GB
Any help/ideas will be appreciated.

I hear that it's getting stable. I personally prefer using XFS on Linux
filesystems that need quotas, but I haven't used quotas on ext3 in a
while.
