Quotas not working after reboot

[Edgaras Lukoševičius]

Hello,

after rebooting my dovecot server quotas are no longer working.

# dovecot --version
2.2.10

CentOS Linux release 7.0.1406

It is strange that restarting dovecot did not reveal this problem, but rebooting whole server did.



Before reboot it was like this:

# doveadm -D quota get -u test1 at testdomain1.tld
