I'd want to do some serious testing before using XFS in your environment.
Is there a reason you can't use ext3?
No. I want to test it before using it at customer sites. At one cutomer
the fsck on ext3 takes 2 hours - they are losing money.

  XFS is needed in situations where
you are losing data and or money while systems are down (remote sensing
and other time-critical high-volume data collection, numerical simulation,
video production, etc.).  I'd venture that most heavily used XFS systems
are not using (register-starved) ix86, and are using SCSI, FC, or SAS
storage.  You aren't getting the full benefits of all the testing that
has been done.

Does that mean there should not be problems on scsi-storages?

There should not be problems using ide storage, but I don't think xfs has been exercised as completely (e.g., the really exceptional cases) on low-end hardware, so we don't really know if the people who say it works for them were just lucky. I've had to use xfs_repair a few times on SGI machines after a kernel oops or similar rare event, but only once on a PC. In the latter case the system didn't have enough memory for xfs_repair to run, so I really don't know if it would have worked given more than the 256M that was considered generous when the PIII was young.
