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 at 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 at mail-004 mdbox]# du storage/
194788 storage/
[root at 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 at mail-004 mdbox]# doveadm purge -A
[root at mail-004 mdbox]# du storage/
142072 storage/
[root at 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 at mail-004 mdbox]# cd storage/
[root at 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 at mail-004 mdbox]# doveadm purge -A
[root at mail-004 mdbox]# cd storage/
[root at 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 at mail-004 storage]# doveadm dump
/var/vmail/example.org/user/mdbox/storage/ | grep 'ref.*\b0\b'
[root at mail-004 storage]#
The index is updated only after the second run of doveadm purge -A ?
Best regards,
Morten
