Hi,

After a hard drive issue from my VPS provider, one of my customers' mailboxes has been corrupted, and has been complaining about index sync issues.  So I am attempting a force-resync.

The command I used was:

doveadm -v force-resync -u user@mailbox.com '*'

The output it's been giving doesn't look anything like a 'progress counter', so I have no idea if it's just losing its mind, or if it's actually achieving anything.  The mailbox is 20G, so theoretically it's just working its way through it, but I can't tell.

The output looks like:

doveadm(user@mailbox.com): Warning: fscking index file /home/mail/mailbox.com/user/mdbox/storage/dovecot.map.index doveadm(user@mailbox.com): Warning: mdbox /home/mail/mailbox.com/user/mdbox/storage: rebuilding indexes doveadm(user@mailbox.com): Warning: Transaction log file /home/mail/mailbox.com/user/mdbox/storage/dovecot.map.index.log was locked for 90 seconds (mdbox storage rebuild) doveadm(user@mailbox.com): Warning: fscking index file /home/mail/mailbox.com/user/mdbox/storage/dovecot.map.index doveadm(user@mailbox.com): Warning: fscking index file /home/mail/mailbox.com/user/mdbox/storage/dovecot.map.index doveadm(user@mailbox.com): Warning: mdbox /home/mail/mailbox.com/user/mdbox/storage: rebuilding indexes doveadm(user@mailbox.com): Warning: Transaction log file /home/mail/mailbox.com/user/mdbox/storage/dovecot.map.index.log was locked for 90 seconds (mdbox storage rebuild)

It's just this over and over and over and over.

Does this mean it's working, or that something else is going on?

fuser /home/mail/mailbox.com/user/mdbox/storage/dovecot.map.index.log shows only the PID of the force-resync, and ls -l /proc/pid/fd shows it has a bunch of index and index.log and index.cache files open, as well as scrolling through mdbox/storage/m.{digits} a bunch, and strace -fp on the process shows a boatload of pread64 on those m.{digits} files, so I *think* it's working, but I can't tell if it's just restarting after the above messages and doing the same thing over and over again.

I've locked the mailbox so there's no mail delivery being attempted on it, and changed its password and kicked out any logged in users on the mailbox, so the only process anywhere near that entire directory structure is the force-resync.

Thanks,

Justin
