[Dovecot] 1.2.4 Maildir Quota Issues
Has anybody noticed this behavior when using maildir quota with Version 1.2.4: # 1.2.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686-bigmem i686 Debian 5.0.3 xfs
My default configurations quota configurations: plugin: quota: maildir:User quota quota_rule: *:storage=2G
Customized Use Configurations at the Mysql level:
user_query = SELECT 5000 AS uid,5000 AS gid,'/vmail/%d/%n' as home,
concat('*:storage= ', virtual_users.quota_kb) AS
quota_rule
from virtual_users LEFT JOIN virtual_domains ON
virtual_users.domain_id=virtual_domains.id
where virtual_users.user='%n' and virtual_domains.name='%d'
When I change quota at the SQL level (per user), that quota becomes active once Dovecot is restarted. Until then it keeps the previous quota assigned. I do not remember seeing this behavior in previous versions --quota was active after sql changes.

This likely has something to do with the auth_cache value.
Try on a fresh user, change it, try 2 minutes before auth_cache would expire, and then again 2 minutes after.

Hi Mario,
You could try setting it to value of "0" not too sure on what performance impact you might get though (Timo??) As it asks the database every time you connect, if you run replication and query localhost, I doubt anything degrading, if you don't run replication and your mysql server is real busy, you might experience a slight to noticeable performance impact.
Cheers Noel

You can reset auth cache by sending dovecot-auth process SIGHUP. I'd
guess changing quota values is somewhat rare so this shouldn't be much
of a performance issue. Anyway, the whole point of auth cache is to
cache the lookups so everything is working as it should..
Timo,
Thanks ! Just looking for a way to scripting the resetting of the auth-cache .. I noticed the dovecot-auth process does not have a PID file as the Dovecot master has (or perhaps I missed it ...)
In a debian machine (running Version 1.2.4) Could I just grab the pid number from the auth socket:
ls /var/run/dovecot/auth-worker* | sed 's/.*auth-worker\.//' 10650
cat /var/run/dovecot/master.pid 10649
ps -ef | grep auth root 10650 10649 0 Sep12 ? 00:00:03 dovecot-auth root 10656 10649 0 Sep12 ? 00:00:00 dovecot-auth -w
These are the contents of /var/run/dovecot/ (3 sockets and one PID file : auth-master auth-worker.10650 dict-server master.pid
Regards,
M.A.

Right, it doesn't. Hmm. Wonder if there should .. Kind of annoying to
pollute multiple PIDs there.
No, that's auth worker's PID and the auth cache is in the main dovecot- auth process.
I just do killall -HUP dovecot-auth :)
