dovecot - Jun 2011 - save failed to INBOX: Not enough disk space

Hi
I migrated to dovecot 2 and I started using lmtp for mail delivery.


But I have found this on my logs "save failed to INBOX: Not enough disk
space" .

There is enougth space on disk. and I am not using quota plugin on lmtp

my lmtp conf is as follow:

#
## LMTP specific settings
##

# Support proxying to other LMTP/SMTP servers by performing passdb lookups.
#lmtp_proxy = no

# When recipient address includes the detail (e.g. user+detail), try to save
# the mail to the detail mailbox. See also recipient_delimiter and
# lda_mailbox_autocreate settings.
#lmtp_save_to_detail_mailbox = no

protocol lmtp {
  # Space separated list of plugins to load (default is global mail_plugins).
  #mail_plugins = $mail_plugins
mail_plugins = sieve
postmaster_address = admin at domain.tld
}

Any idea please?

Thanks

Hello!
And you have free inodes too and you don't have quota on filesystem? I'm
asking to be sure:)
Regards!

Hi again

Sorry if I top post, but this problem is urgent as we are losing mails.

We have migrate from dovecot 1.4 to dovecot 2.0.12. But from severals
now we have found this on our log files.

relay=smtp1.huissier-justice.fr[private/dovecot-lmtp], delay=5.4,
delays=0.74/0/0.01/4.6, dsn=5.2.2, status=bounced (host
mail.domain.tld[private/dovecot-lmtp] said: 552 5.2.2
<user1 at domain.tld> Not enough disk space (in reply to end of DATA
command))

We use maildir on an ocfs2 filesystem shared by 4 serveurs. The
partition is not full the output of df -hi is:

#df -hi
Filesystem            Inodes   IUsed   IFree IUse% Mounted on

/dev/mapper/vmail
                        30M     21M    9.2M   70% /var/vmail

We noticed this happens when messages are bigger than 5Mbytes, but
are not using quota plugins on dovecot-lmtp

this is a part of our dovecot configuration.


service lmtp {
  chroot   client_limit = 0
  drop_priv_before_exec = no
  executable = lmtp
  extra_groups   group   idle_kill = 0
  inet_listener lmtp {
    address = 127.0.0.1 ::1
    port = 24
    ssl = no
  }
  privileged_group   process_limit = 0
  process_min_avail = 0
  protocol = lmtp
  service_count = 0
  type   unix_listener /var/spool/postfix/private/dovecot-lmtp {
    group = postfix
    mode = 0660
    user = postfix
  }
  unix_listener lmtp {
    group     mode = 0666
    user   }
  user   vsz_limit = 0
}

protocol lmtp {
  mail_plugins = sieve
  postmaster_address = admin at domain.tld

In postfix main.cf

mailbox_size_limit = 0
virtual_mailbox_limit = 51200000


Any ideas Please?

Thanks

Hi
the output of df -h is:

Filesystem            Size  Used Avail Use% Mounted on

/dev/mapper/vmail
                      120G   84G   37G  70% /var/vmail

Thanks for your help.

This means that a write() (or some other syscall) returned either ENOSPC
or EDQUOT error message, or that quota plugin decided user is out of
quota.

What about filesystem quota?

A full doveconf -n output would be better.

Actually quota plugin gives a different error message. The only
possibility I can think of is that ocfs2 has decided to start returning
"no disk space" failures when Dovecot tries to create files.

Does this happen for every mail delivery? Can you manually create more
files? Can you upload messages via IMAP (i.e. is it only LMTP that is
the problem?

Hi

Doing mail debug I found this

dovecot: lmtp(12696, user1 at domain.tld): Error:
o_stream_send_istream(/var/vmail/domain.tld/user1/Maildir/tmp/1307537596.M117043P12696.smtp1)
failed: No space left on device

dovecot: lmtp(12696, user1 at domain.tld): Error:
o_stream_flush(/var/vmail/domain.tld/user1/Maildir/tmp/1307537596.M117043P12696.smtp1)
failed: No space left on device


So dovecot write in to a tmp folder inside the user Maildir before
definitly copying it to new folder.

But why it says thereis no space left?
