Nope, plain ext3. I have these issues since upgrading to Ubuntu 11.10, which was a dovecot upgrade from 1.2.15 to 2.0.13. Currently I use a self-built 2.0.15 dovecot. I'm still getting errors once in a while for the dovecot.index.log file:
Nov 4 16:29:03 keira dovecot: imap(isa): Error: fcntl(unlock) locking failed for file /home/dovecot/isa/dovecot.index.log: No such file or directory Nov 4 16:29:03 keira dovecot: imap(isa): Error: fstat() failed with file /home/dovecot/isa/dovecot.index.log: No such file or directory
These simply shouldn't happen. I'd say it's a kernel bug. You're running a default Ubuntu kernel? I wonder if other Ubuntu users have this problem.
And occasionally I also get errors like:
Nov 3 19:03:34 keira dovecot: imap(mikey): Error: Corrupted transaction log file /home/dovecot/mikey/dovecot.index.log seq 15: offset points outside file (32708 + 8 > 32708) (sync_offset=32800)
I believe the latter was recently reported by someone else on this list as well. The files are there, though I guess that dovecot recreates them when the errors occurs so I don't know what the situation was by the time the error occurred...
Try if you can reproduce these more easily with imaptest? http://imapwiki.org/ImapTest Be sure to run it against a test account since it trashes the whole mailbox.
