Hi, its the second time in 6 Month i have issues with a huge mdbox. It broken in November and i restored from backup because force-resync twice didnt fix it. (And restore from borg-backup was MUCH faster than force-resync)
This time i have heavy delivery into that mailbox (postfix concurrency 1) and i tried merging folders with doveadm move. The move froze and now i seem to have a broken mdbox:
Errors are:
May 05 10:21:09 lda(inbox@wasteland.rfc822.org): Error: Log synchronization error at seq=2736,offset=135540 for /var/vmail/wasteland.rfc822.org/inbox/mdbox/storage/dovecot.map.index: Extension record inc drops number below zero (uid=7757856, diff=-1, orig=0)
trying
root@pax:~# doveadm -D -v force-resync -u inbox@wasteland.rfc822.org \*
now. Although this will mostly likely take 8-10 hours.
Mailbox is 44GByte (Compressed mdbox) and 220K folders.
This is dovecot on Debian/Stretch
