One annoying problem about v2.0's doveconf -n output is that it hides when using multiple var=$var lines.. Did you have more plugins than just quota enabled?
Should I set mail_fsync for only pop and imap instances? Currently I don't use Dovecot's lmtp or deliver, but will, so there I can't allow disabling fsync. I don't like setting this to never, but after a migration from courier, the machine couldn't handle the load with fsync, so this is a must.
Yeah, either set it to only protocol imap/pop3 {} or alternatively put mail_fsync=no to protocol lda/lmtp {}.
BTW, just curious, what is the rationale of the two fstats so close together?
It's because of how the code works internally. It would be too much trouble to avoid the second call and would make the code uglier. fstat() is cheap anyway.
I've searched for some more examples and each of them were like this one. It seems that Dovecot copies the subscriptions file to this temporary file and then fsyncs it. And the question also arises: why?
Fixed: http://hg.dovecot.org/dovecot-2.0/rev/4959db811d29
Also http://hg.dovecot.org/dovecot-2.0/rev/432208994270 avoids multiple write() syscalls. Although it still does writes to temp file even when it's not necessary, but that's again annoyingly too much trouble to prevent..
And more specifically: why in a pop3 server?
Do you have autocreate plugin enabled with autosubscribe plugin settings? You didn't show your full doveconf output so I have to guess..
