We had a server barf on a Reiser3 file system on a RAID5 array, and it
was unrecoverable. After we rebuilt it with ext3, one month later the
SCSI RAID controller died, so I suspect it was much less Reiser's fault
than hardware.
Software can only perform as well as the hardware on which it runs, so
just be sure your hardware is in good shape. We have a busy mail
server running on Reiser and have had no issues, even when replacing
failed disks in the RAID array (no downtime).
Having said that, my understanding from the last time I Googled this
stuff is that ext3 journals capture more metadata than Reiser3, so
(theoretically), you should have more opportunities to recover fully
from a bad file system error with ext3 than with Reiser3, at the cost
of some performance in writing that extra metadata.
Bottom Line is we have no preference between the two, have tried
building servers with both and probably because we insist on using
top-quality server hardware, we've had only one show-stopping issue
(with Reiser3) that was probably more due to hardware going bad than
anything else.
End Note: When the SCSI RAID controller died, we replaced it with an
identical unit, turned the server on and SuSE SLES9 booted just fine
with just a few transactions replayed. It's been up for about a year
since, rebooted only for kernel updates.
YMMV,
Mark
