dovecot - Sep 2018 - dovecot.index.pvt reset

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

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?

TIA!

Chris

This happens because the index.pvt is no longer valid, because you rm -rf'ed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

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