Hi,

We are currently testing Dovecot 2.0.13 with mdbox. If I delete large objects with refcount=0 the index is not updated apparently.

Here's an example:

[root@mail-004 storage]# ls -l total 194776 -rw------- 1 vmail vmail 482960 Jul 9 14:58 dovecot.map.index -rw------- 1 vmail vmail 4584 Jul 9 16:06 dovecot.map.index.log -rw------- 1 vmail vmail 32856 Jul 9 14:50 dovecot.map.index.log.2

[root@mail-004 mdbox]# du storage/ 194788 storage/

[root@mail-004 mdbox]# doveadm dump /var/vmail/example.org/user/mdbox/storage/ | grep 'ref.*\b0\b'

• ext 3 ref : 0 (0000)
• ext 3 ref : 0 (0000)
• ext 3 ref : 0 (0000)
• ext 3 ref : 0 (0000)
• ext 3 ref : 0 (0000)
• ext 3 ref : 0 (0000)
• ext 3 ref : 0 (0000)
• ext 3 ref : 0 (0000)

[root@mail-004 mdbox]# doveadm purge -A [root@mail-004 mdbox]# du storage/ 142072 storage/

[root@mail-004 mdbox]# doveadm dump /var/vmail/example.org/user/mdbox/storage/ | grep 'ref.*\b0\b'

• ext 3 ref : 0 (0000)
• ext 3 ref : 0 (0000)
• ext 3 ref : 0 (0000)
• ext 3 ref : 0 (0000)
• ext 3 ref : 0 (0000)
• ext 3 ref : 0 (0000)
• ext 3 ref : 0 (0000)
• ext 3 ref : 0 (0000)

[root@mail-004 mdbox]# cd storage/ [root@mail-004 storage]# ls -l total 142060 -rw------- 1 vmail vmail 482960 Jul 9 14:58 dovecot.map.index -rw------- 1 vmail vmail 4584 Jul 9 16:06 dovecot.map.index.log -rw------- 1 vmail vmail 32856 Jul 9 14:50 dovecot.map.index.log.2

[root@mail-004 mdbox]# doveadm purge -A [root@mail-004 mdbox]# cd storage/ [root@mail-004 storage]# ls -l total 142060 -rw------- 1 vmail vmail 482960 Jul 9 14:58 dovecot.map.index -rw------- 1 vmail vmail 4936 Jul 9 16:12 dovecot.map.index.log -rw------- 1 vmail vmail 32856 Jul 9 14:50 dovecot.map.index.log.2

[root@mail-004 storage]# doveadm dump /var/vmail/example.org/user/mdbox/storage/ | grep 'ref.*\b0\b' [root@mail-004 storage]#

The index is updated only after the second run of doveadm purge -A ?

Best regards,

Morten
