I know this is a difficult theme, and test results may controversial, but it shouldnt be a point for hot flames so it may be better, doing it offlist. Meanwhile why dont just post real working storage/filesystems examples with big used dovecot setups, which may help everybody, perhaps in the wiki After all we decide doing a big test setup to clear all this questions. -- Best Regards MfG Robert Schetterer
[Dovecot] Timeout (180s) while waiting for lock for transaction log file
Hello,
We still have problems with our updated dovecot servers... The problem
now is that we are having errors like:
Jul 9 10:22:02 myotis31 dovecot: lmtp(15431, user): Error: Timeout
(180s) while waiting for lock for transaction log file
/var/indexes/user/.INBOX/dovecot.index.log

Jul 9 10:22:02 myotis31 dovecot: lmtp(15431, user): Error:

failed with unsuccessful implicit keep (user logfile
/home/pdi/88/185188/.dovecot.sieve.log may reveal additional details)
in the .dovecot.sieve.log all we have is just:
sieve: info: started log at Jul 09 10:22:02.
error: msgid=4ffa8700.2080...@um.es: failed to store into mailbox
'INBOX': Internal error occurred. Refer to server log for more
information. [2012-07-09 10:19:02].
maildir are in a nfs storage, but indexes are in local disk. I don't
know if the problem could be related with a some specific messages or
something specific to the user, because we are having this problem only
with a few users and the problem repeatedly happens when our mta tries
to deliver the queued message.
Any idea?

Seem some people have never heard of keep it simple, stupidor less is more ... sounds like a few people here are falsely propping up their worth to their employers, making unnecessary BS to justify their own existence. My experience of over 20 years of this industry easily shows that those who try to make complex networks _always_ have far higher fail rates than those that keep it simple, nearly never have any problems, and when they do its because the powers failed, the gennies didnt kick in and UPS's died before engineers got the gennies going. I've also seen most networks that use SAN's have a far more problems than those using NAS's - providing you use decent NAS gear like EMC or Netapp :) Don't evne think about using a general server as a NAS.

Re: [Dovecot] Howto add another disk storage
what you do not understand is that a proper SAN is NOT an complex setup, it is in many cases a simpler one because you have TWO controllers, disks with DUAL channel and a proper RAID level in ONE device to built all this redundancy at your own is a much complexer software-setup and you can be pretty sure taht as long you are not dealing night and day with storage/Failover-setups the people designing a SAN have much more expierience what the are doing Am 09.07.2012 12:01, schrieb Noel Butler: Seem some people have never heard of keep it simple, stupidor less is more ... sounds like a few people here are falsely propping up their worth to their employers, making unnecessary BS to justify their own existence.

[Dovecot] configuring imap_stats
Hi,
i'm trying to configure imap_stats like it's documented in the wiki:
http://wiki2.dovecot.org/Statistics. But as soon as i activate the
imap_stats plugin i get the following error message trying to login via
imap:
dovecot: imap: Error: Can't load plugin imap_stats_plugin: Plugin stats
must be loaded also (you must set: mail_plugins=$mail_plugins stats)
But the stats plugin is configured as you can see in the attached
configurations. Also i can get statistics without the imap_stats
enabled, but as far as i know only of the pop3 users.
Kind regards

It's definitely the same problem.
The patch mentioned in that thread to solve the problem
(https://bugzilla.redhat.com/attachment.cgi?id=570690action=diff#a/fs/eventpoll.c_sec1)
consist on adding:
static int path_count_inc(int nests)
{
if (nests == 0)
return 0;
to the begining of path_count_inc function at fs/eventpoll.c in kernel
source.
I have checked that 3.2.0 kernel I have and this patch is already
applied.
Any other idea? Is there anybody running dovecot with a
ubuntu/debian/vanilla (not redhat based) kernel? What kernel?

I have found a similar problem at https://bugzilla.redhat.com/show_bug.cgi?id=681578 but it is for redhat kernel of series 2.6. Could be the same problem? It's definitely the same problem. Any pointer to this problem for ubuntu kernels? Or for generic 3.0 kernels? Sorry, no idea. in case its fixed in some more recent versions http://kernel.ubuntu.com/~kernel-ppa/mainline/ guess this is latest for 12.04 http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-precise/ -- Best Regards MfG Robert Schetterer
Re: [Dovecot] mailboxes missing after upgrade from 2.1.4 to 2.1.7
Micah Anderson mi...@riseup.net writes: I mentioned this on the #dovecot irc channel, but I thought I would post here so I can provide more details. The basic problem is that when I upgraded from 2.1.4 to 2.1.7, some users no longer are able to see their folders in pine/alpine. The folders are actually there, and are subscribed (according to doveadm) and its possible to do operations on those folders, if you know the name (for example, opening the folder works fine if you know the name). When I downgrade to 2.1.4 again, the folders appear again, so its clearly something that changed between the two versions. I looked through the changelog, and found a few possibile culprits, I think pine/alpine use imapc, so that could be related: I was able to solve this by changing the alpine folder-collection configuration to *not* have /INBOX.[] at the end and instead have just []! micah
Re: [Dovecot] configuring imap_stats

Hi,
i'm trying to configure imap_stats like it's documented in the wiki:
http://wiki2.dovecot.org/Statistics. But as soon as i activate the
imap_stats plugin i get the following error message trying to login via
imap:
dovecot: imap: Error: Can't load plugin imap_stats_plugin: Plugin stats
must be loaded also (you must set: mail_plugins=$mail_plugins stats)
The global mail_plugins setting should contain:
mail_plugins = quota stats
And protocol imap's mail_plugins setting should contain:
mail_plugins = $mail_plugins imap_quota imap_stats
The $mail_plugins inside protocol imap {} will be expanded to the value
of your global mail_plugins setting.
,--[ doveconf -f protocol=imap mail_plugins ]--
| mail_plugins = quota stats imap_quota imap_stats

[Dovecot] recover .sieve plaintext from .sievec binary file
Hi, I upgraded a server from an old Linux distribution to a much newer one. In the process, Dovecot got upgraded from v1 to v2. By mistake, I deleted the .sieve plaintext file with all the Sieve filters, but I still do have the .sievec compiled binary. Is there any way to dump the binary file back into plaintext format? Keep in mind, I'm running v2 now, and the binary was made on a v1 Dovecot server. Thanks. -- Florin Andrei http://florin.myip.org/

That binary is produced by the old cmusieve plugin. You'll need the old sieved tool to dump the binary. And then you still have a problem. The sieved tool does not reconstruct the sieve script that was used to create it; it produces an assembly-like output from the byte code. You'd have to manually translate that back to Sieve. :/ Regards, Stephan.

Now I'm sure you'll tell us why Google doesn't count for some reason in this discussion, why their use of SATA isn't relevant somehow. -- Stan
