Hello, Ok, I had a three week test period with 2.6.17.1 + the xfs-fix for
kernel bug #6757 (that one is really needed and IMHO should go into a stable
kernel patch as soon as possible!) + sws2 2.2.6. One week with disabled write
caches, one week with enabled write caches and barrier mount option mentioned
in /etc/fstab, one week with enabled write caches and barrier mount option not
mentioned in /etc/fstab thus specifically testing whether its really the
default now.
No problems. xfs_check on the root partition showed three agi unlinked bucket
that xfs_repair fixed but from what I know these are no real defects. If that
shouldn't happen tough, something till needs to be fixed. Please tell me if
thats the case.
I added to that three tests with switching off the computer while writing data
to a XFS partition:
1) rsync -a /usr/src /destination/partition
2) ddrescue /dev/hda1 /destination/partition
3) 1 + 2 + rm -rf /that/usr/src/directory-from-test-one. The rm job was
completed a second before I switched off the laptop, but I am sure that the
other jobs were still running
Result: No problems. No single line of output in xfs_check after each of the
three tests.
So I am pretty much convinced that XFS is working really stable now with write
caches given that the patch from kernel bug #6757 which is unrelated to the
write cache issue is applied.
Thank you, guys!
Regards, Martin
