Hello, Has anyone used GlusterFS as storage file system for dovecot or any other email system..? It says that it can be presented as a NFS, CIFS and as GlusterFS using the native client, technically using the client would allow the machine to read and write to it, therefore, I think that Dovecot would not care about it. Correct? Anyone out there used this setup?? Thanks.

I wouldn't use it without some heavy stress testing first (with imaptest tool).

The two reasons are high latency and problems with file locking, as Timo mentioned. Instead of asking if anyone here has tried to use GlusterFS, why not describe your situation and ask for advice on a solution? That usually works much better, and you gain valuable insight. -- Stan

We've considered using gluster for our mail storage a month ago. I've seen index corruption even if mail was delivered by lmtp sequentially some split-brains with no clear reason with more than 2000 mails in box we had to wait for 40sec to open mailbox through roundcube, so we've decided to go for dsync replication instead with common mysql database for user storage and imap/pop3/lmtp proxy. -----Original Message----- From: dovecot-bounces at dovecot.org [mailto:dovecot-bounces at dovecot.org] On Behalf Of Romer Ventura Sent: Thursday, June 21, 2012 2:51 AM To: dovecot at dovecot.org Subject: [Dovecot] GlusterFS + Dovecot Hello, Has anyone used GlusterFS as storage file system for dovecot or any other email system..?
