and a few more optimizes about maildir

how many clients ?

i started the server not long ago so they are less yet ( about 100 maildirs ) but i have my own account in it which has massive mails ( 10 GB store with over 1000 mails daily in out , and perhaps 10000 mails in store)

sorry, i did not say i use dovecot 2.0.6

looks fine, update to 2.0.8 if ready

did you use the mail option at ocfs2 store creation ?

what os/distro do you use , i remember bugs with ocfs with some distro versions

Robert, are you running an active-active setup with drbd+ocfs2?

Have you ever seen errors like these in the logs?

Thanks, Andre

hi Andre, no never seen such, i have full possible debugging enabled a grep "synchronization error" or "Corrupted transaction" finds nothing in the logs
