We are in the process of migrating our mail store from CentOS-6.9
running Cyrus-IMAPD-2.3.16 to FreeBSD-11.1 running Cyrus-IMAPD-3.0.5.
I am observing several behaviours that strike me a odd and which
likely indicate that something is wrong with my procedure.
I have tried moving things over using imapsync-1.836 and while this
appears to work we end up with vastly enlarged user mailbox sizes.
Also I cannot see the quota setting for most users although a few are
I then restarted the process and used rsync natively with --hard-links
in order to see if that reduced the disc space. Following the rsync of
all the user mailboxes I re-initialised
I have run 'reconstruct -fr user' and rebuilt mailboxes.db. This is
what I get from running 'quota -f user' thereafter:
[root at inet17 /var/spool/imap]# sudo -u cyrus
/usr/local/cyrus/sbin/quota -f user
Quota % Used Used Resource Root
[root at inet17 /var/spool/imap]#
At a guess this means that all of the user mailbox quota settings are
gone. However, I would expect the usage to be shown. And is there
not a default quota?
