I don't know about any problems with ReiserFS, except in case of hardware
errors. It is default on thousands of SuSe installations.
I'd better avoid XFS as _not enough customers use it_. Since SLES10, ext3
can be used because it have online resizing (primitive, through); before
SLES10, ReiserFS is the only stable file system except ext3.

I see on the following Metalink Note 414673.1 that both ext3 and XFS are
Suse provided filesystems that support both Asynch and Direct I/O on SLES-9
and SLES-10 on 10g databases.
I recently lost a resierFS filesystem to reiserfsck --rebuild-tree when tons
of reiser kernel cannot stat errors started showing up in /var/log/messages.
A colleague of mine had the same thing happen to him recently and said he
did warn me about reiserFS. I used the manufacturer's CD to run a low level
diagnostics of the drive, and there were no bad sectors or any other
problems found.
I am looking for a stable, high performance filesystem for hosting 10g
Oracle Applications databases, but may also host the Applications tiers
which consist nearly 1 million files per instance.
Are there formatting options that people use when creating ext3 or XFS
filesystems for Oracle that seem to improve performance? In my testing
using the default formatting options comparing ext3 and reiserFS filesystems
belonging to the same LVM groups, read speeds were comparable, but reiserFS
was 2x faster on writes in Iozone benchmarking. Most write intensive ERP
jobs took longer on ext3 as well. Online LVM resize was pretty cool as
well.
I have come down from my ReiserFS soap box since the filesystem has gone
into maintenance mode and I was burned last week. I am just wondering what
the community's comments on this topic would be with reiserFS out of the
picture.
Thanks,
Michael
