      At least I think it is related since I got my 2 Kopano servers down this morning with the following log entries after reboot :

      I can’t see what is going wrong, might be OS related…

        MariaDB on Debian 10 is a bit unforgiving. To fix this, commit https://stash.kopano.io/projects/KC/repos/kopanocore/commits/2944c0e57103647a882a378eb796519030e013ed is required.

          Thanks. I got one Kopano server back. The other doesn’t give the SQL error anymore neither but gets stuck on this :

          This has nothing to do with the previous issue of course but still stops the kopano-server service from starting. I don’t understand, my permissions are ok and also tried resetting them with chown -R kopano:kopano /mnt/sdb/kopano/attachments but still the same… This worked before (server is in prod since a few months)…

            I’ll close this one here and open a new one as this is not related to the original issue anymore.
