All,

maybe that's a similar issue like the one mentioned in [1], nevertheless I started a new thread.

Using public folders:

location = maildir:/var/vmail/public/:LAYOUT=fs:INDEXPVT=%h/.public-indexes

When deleting a public maildir in filesystem (rm -rf ...) and copying back from backup, it's older than the users' dovecot.index.pvt files. (%h is in another directory). Then the following error appears:

Sep 19 07:27:00 mail1 dovecot: imap(dr): Error: /var/vmail/users/dr/.public-indexes/folder1/folder2/dovecot.index.pvt reset, view is now inconsistent

This happens because the index.pvt is no longer valid, because you rm -rf'ed things.

Sometimes even a panic:

Sep 19 07:27:00 mail1 dovecot: imap(dr): Panic: file mail-index-map.c: line 548 (mail_index_map_lookup _seq_range): assertion failed: (first_uid <= last_uid)

When deleting such a maildir via IMAP or doveadm, the error isn't appearing.

Is there anything else, one has to consider, when restoring public maildirs from rsync backup?

rm all the dovecot.index.pvt files. The assert-crash should probably not happen at all.

TIA!
