[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/

SATA drives are being used very widely in production today, and outnumber SAS deployments by a very wide margin. For instance, web servers, counting in the 10s of millions worldwide, use SATA drives exclusively, where RAM is critical for performance, not disk. You won't find SAS drives in web farms simply due to cost. Everyone doing D2D backup and nearline storage is using SATA today. And most everyone, from large enterprises, to K-12 schools, to SOHOs, use SATA drives in front line file servers. SAS is found today almost exclusively in high volume transactional servers such as mail spools, mail stores, databases, VM image storage, and applications that need higher reliability, such as medical imaging systems, etc. -- Stan

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.

Could be the same problem?
It's definitely the same problem.
The patch mentioned in that thread to solve the problem
(https://bugzilla.redhat.com/attachment.cgi?id=570690&action=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?

[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

Fortunately you do not decide about it.
i do not sell them and i am not uneducated
The wording they use ("everyone do this", "because it is enterprise") just
proves that most of them are people that
should not even touch a computer
look in the mirror after your off-list explanations why
i am talking both about your off-list and on-list conversation in which
you prove all your "knowledge" is advert based.
Words like "mainstream", "enterprise", etc. are just marketing
words, and should not be used in technical discussion having no meaning. Using them
prooves lack of real knowledge, and that's what you exactly did.
Saying to me - a regular massive user of cheap ATA/SATA drive in
production since 14 years - that "nobody" use them in production is just
funny!
But OK - you at least plan disaster recovery. Rare event.
Your clients after paying huge money to get high complexity and low
performance, AT LEAST will not loose data.

Re: [Dovecot] Howto add another disk storage
Many people just want to be proud, or want to make things expensive so their
clients are proud. but not always it's like that.
You go on a bit about "pride in complexity" . . What you fail to understand is
that many highly intelligent, experienced, very able engineers build systems that are as
complex and as large as they _need to be_ and just because you don't deal with such large
systems doesn't make everyone else wrong. (Okay, I know, some people are proud, and some
people do make bad decisions about large complex systems -- but you make the mistake of
assuming everyone does.)
there are lots of skilled engineers here on that forum.
But certainly not the ones that babble about storage, SANs etc.. just because they sell
them, have profits from selling them or are just that uneducated.
The wording they use ("everyone do this", "because it is enterprise") just
proves that most of them are people that should not even touch a computer.
Sadly that's majority of "specialists" nowadays.
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, stupid"or > "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.

Re: [Dovecot] Howto add another disk storage
Seem some people have never heard of "keep it simple, stupid"or "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
ouch - that said and your offlist discussion why SAN storages are crap for you gives a picture - nobody, really nobody is using SATA for any production-storage In a view of moron you are "everyone".
Re: [Dovecot] Howto add another disk storage
using SATA for any production-storage Hi, sorry SATA is running fine here, as well here. Many people just want to be proud, or want to make things expensive so their clients are proud. but not always it's like that.
[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, ): Error: Timeout
(180s) while waiting for lock for transaction log file
/var/indexes//.INBOX/dovecot.index.log

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:

'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?

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
