Hi,

we had the same problem after a system failure. Our problem could be solved by

rm /PATH/USER/mdbox/storage/dovecot.map.index* doveadm -D -v force-resync -u USER INBOX

Best regards, Gordon

Hi,

On saturday one of our dovecot machines had an OOPS, and we had to powercycle it. When it came up, it did a filesystem fsck (ext4) and fixed a couple things, but nothing in lost+found.

Now, about 50 users have a problem where their indexes are corrupted. Dovecot tries to fix them, but for some reason it is failing. The users are seeing their mails duplicated and they cannot delete mails. I can see in the logs dovecot detecting this and trying to rebuild operations during delivery and imap login, but its repeating over and over and over. For one user, I've seen more than 4k lines in the logs about this.

If i try to do doveadm force-resync -u username INBOX

I get this:

doveadm(nuffsaid): Warning: mdbox /n/nuffsaid/mdbox/storage: Inconsistency in map index (3494,32332 != 3494,383536) doveadm(nuffsaid): Warning: fscking index file /srv/dovecot_indexes/n/nuffsaid/storage/dovecot.map.index doveadm(nuffsaid): Warning: mdbox /n/nuffsaid/mdbox/storage: rebuilding indexes doveadm(nuffsaid): Warning: fscking index file /srv/dovecot_indexes/n/nuffsaid/storage/dovecot.map.index doveadm(nuffsaid): Warning: mdbox /n/nuffsaid/mdbox/storage: Inconsistency in map index (3494,32332 != 3494,384024) doveadm(nuffsaid): Warning: fscking index file /srv/dovecot_indexes/n/nuffsaid/storage/dovecot.map.index

but then if i do it again, I get the same thing, over and over and over (the numbers change a little).

This is dovecot 2.2.27 with mdbox format.... what can I do to fix this? Its driving users mad, and they keep going over quota as their space fills.

thanks! micah
