<p class=MsoNormal><font size=3 color=black face="Times New Roman"><span
style='font-size:12.0pt'>I've been using ext4 on both the "big/slow"
SATA array and the "small/fast" SAS array in the file server I run at
work for the better part of a year now. I performed unspeakable tortures
on it before I put the system into production but even the automated
disk-to-disk backup that takes place every night (especially the
first-of-the-month one that makes a >400GiB squashfs image) as well as the
occasional ClamAV scans and searches definitely load things up. To date
the only problem that I have had with the server at all was probably
attributable to either Samba or a stray bit flip affecting Samba, not ext4, and
it was cured with a Samba restart. In fact, I had occasion to bring the
eight-drive RAID1+0 SATA array down recently after 208 days of continuous uptime
and gave it a fscking before mounting it, and it was fine. That being
said, I'm not seeing a downside to ext4, at least not yet. Granted,
perhaps there are applications where XFS, JFS, etc. would work so much better
that it would be worth occasional strangenesses, but a big file server for
mostly WinTel desktop/laptop clients isn't one of them. <br>

I'm consulting at a company that wants to turn their Linux based NAS in to a
reliable product. They initially chose XFS because they were under the
impression that it was high performance but what they got was something of
questionable reliability. I have identified and patched several serious bugs
(2.6.29) and I have a feeling there are more unidentified ones out there.
Furthermore, xfs_check craps out of memory every time so we have to do an
xfs_repair at boot and it takes forever. But today we got into a
situation where xfs_repair can't repair the disk (a raid5 array btw).<br>
<br>
Does anyone out there use xfs? How about a suggestion for a stable replacement.<br>
