Hi all,
We have recently had some power failures have led to corrupt mdbox instances.
Dovecot’s fsck appears to get caught in a loop when the recipient has a large amount of mail. In the example log output below, each “rebuilding indexes” seems to be interrupted by a new IMAP connection.
Later, when our folks realized the issue and blocked access to the mailbox, the index rebuild finished in about 90 seconds.
Is it possible for the fsck to “lock” the mailbox or otherwise protect against this?
Thank you!-Felipe Gasper
