We've been slowly phasing in mail quotas and I've discovered that
the quota usage reported by cyrus doesn't match a du for that same
user. In fact, I can't find any user where the reports *do*
match. Is this a sign of quota corruption, or am I overlooking
something about how the quotas work?
Here are some examples to show what I'm checking:
[root@balrog ~]# du -s /var/spool/imap/e/user/efreem
1068664 /var/spool/imap/e/user/efreem
[root@balrog ~]# du -s /var/spool/imap/a/user/austin
1178924 /var/spool/imap/a/user/austin
[root@balrog efreem]# cyradm --user cyrus localhost
localhost.localdomain> lq user.efreem
STORAGE 904193/2000000 (45.20965%)
localhost.localdomain> lq user.austin
STORAGE 703056/1000000 (70.3056%)
The du utility reports usage in terms of blocks, not bytes. This is a
major drawback of maildir type systems, they can have nasty partial
block overheads.
