Hi list,
We still did not manage to get quota-status working. We're hoping someone can provide some feedback/ideas on how we may investigate this issue further? Is it likely to be a bug fixed in a newer version?
Regards,
Kristian

Hi list,
I am attempting to get quota-status service working, so I can deny email at the initial smtp dialog instead of generating bounces with lda.
I can't seem to get quota-status to return quota_status_overquota, even when an email would put an account over quota.
Quota in general works fine: Jan 22 06:39:23 mail dovecot: lda(xx@yy.dk): msgid=25c5bdb20d58fc4f649f716a947613dc@zz.org: save failed to INBOX: Quota exceeded (mailbox for user is full) Jan 22 06:39:23 mail dovecot: lda(xx@yy.dk): msgid=25c5bdb20d58fc4f649f716a947613dc@zz.org: rejected: Quota exceeded (mailbox for user is full)
The system is a pretty standard debian 8 box running virtually on a kvm/ovirt cluster: root@mail:~# dpkg --list | grep dovec ii dovecot-core 1:2.2.13-12~deb8u1 amd64 secure POP3/IMAP server - core files ii dovecot-imapd 1:2.2.13-12~deb8u1 amd64 secure POP3/IMAP server - IMAP daemon ii dovecot-lmtpd 1:2.2.13-12~deb8u1 amd64 secure POP3/IMAP server - LMTP server ii dovecot-mysql 1:2.2.13-12~deb8u1 amd64 secure POP3/IMAP server - MySQL support ii dovecot-pop3d 1:2.2.13-12~deb8u1 amd64 secure POP3/IMAP server - POP3 daemon
Mail storage is local XFS partitions as far as the dovecot server knows. Behind the scene its actually raw disk images on NFS shares from a SAN towards the kvm/ovirt cluster.
I test by using nc towards the quota-status instance: root@mail:~# printf "recipient=kptest@asom-net.dk\nsize=1000000000\n\n" | nc -q1 localhost 12340 action=DUNNO
User has 500MB quota: mysql> SELECT CONCAT('/data/vmail/',CONCAT(SUBSTRING_INDEX(email,'@',-1),'/',SUBSTRING_INDEX(email,'@',1))) AS home, 110 AS uid, 110 AS gid, CONCAT('*:storage=',mailquota,'M') AS quota_rule FROM virtual_users WHERE email='kptest@asom-net.dk'; +--------------------------------+-----+-----+----------------+ | home | uid | gid | quota_rule | +--------------------------------+-----+-----+----------------+ | /data/vmail/asom-net.dk/kptest | 110 | 110 | *:storage=500M | +--------------------------------+-----+-----+----------------+ 1 row in set (0.00 sec)
maildirsize seems ok: root@mail:~# cat /data/vmail/asom-net.dk/kptest/maildirsize 524288000S 685 1 690 1
Quota-status will return unknown user if that is the case: root@mail:~# printf "recipient=kptest2@asom-net.dk\nsize=1000000000\n\n" | nc -q1 localhost 12340 action=551 5.5.1 User not found

If I do a strace on the quota-status PID, it seems to do a stat on the directory and then give up? Not sure Im interpreting it correct (only including the last few lines): ... lseek(14, 833, SEEK_SET) = 833 munmap(0x7f165d32a000, 833) = 0 close(14) = 0 geteuid() = 0 getegid() = 110 getgid() = 110 getegid() = 110 setgroups(1, [110]) = 0 setresuid(-1, 110, -1) = 0 prctl(PR_SET_DUMPABLE, 1) = 0 stat("/data/vmail/asom-net.dk/kptest", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 prctl(PR_SET_DUMPABLE, 1) = 0 setsockopt(12, SOL_TCP, TCP_CORK, [1], 4) = 0 write(12, "action=DUNNO\n\n", 14) = 14 setsockopt(12, SOL_TCP, TCP_CORK, [0], 4) = 0 epoll_wait(11, {{EPOLLIN, {u32=1593554016, u64=139734059562080}}}, 5, 59999) = 1 read(12, "", 8146) = 0 epoll_ctl(11, EPOLL_CTL_DEL, 12, 7fff0be817a0) = 0 close(12) = 0 epoll_wait(11, {}, 5, 1000) = 0 write(5, "\35q\1\0007\10\0\0\1\0\0\0", 12) = 12 epoll_wait(11, ...
It seems like sort of permission issue? root@mail:~# su - vmail No directory, logging in with HOME=/ $ id -a uid=110(vmail) gid=110(vmail) groups=110(vmail) $ cat /data/vmail/asom-net.dk/kptest/maildirsize 524288000S 685 1 690 1
/data/vmail/asom-net.dk is actually a symlink, maybe that could be of importance?: root@mail:~# ls -ld /data/vmail/asom-net.dk lrwxrwxrwx 1 root root 19 Jan 9 11:18 /data/vmail/asom-net.dk -> ../mnt1/asom-net.dk

Anyone have any idea what might be wrong here?
