I got some corruption, but not ro changes.
In an early rc nothing seemed wrong until, after a reboot, I saw enough
corruption in a db that I had to dump, clean up several bogus records
and restore it. (It was a busy but ephemeral db, so that wasn't too
much of a problem.
Today, however, running -rc5 the box simply rebooted without notice.
and I got a number of log entries after the reboot. Most specified
ext4_mb_generate_buddy and jbd complained that it spotted a dirty
metadata buffer. There were also a couple of bad header/extents.
I stut down enough to unmoount /var and ran e2fsck. That generated a
*slew* of errors, mostly complaining about multiple files claiming
the same blocks. A second e2fsck right after (with -f) showed no
further errors. I now have about 70 megs of data in lost+found.
The box is only partly up right now (I'm writing this over ssh);
I'll be able to provide more details after a reboot....
