I have not, but can tell you from experience and education that distributed filesystems don't work well with transactional workloads such as IMAP and SMTP. 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

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. reading the faqs i wouldnt recommend it yet, but as Timo said try with performance tests first -- Best Regards MfG Robert Schetterer
Re: [Dovecot] GlusterFS + Dovecot
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-boun...@dovecot.org [mailto:dovecot-boun...@dovecot.org] On Behalf Of Romer Ventura Sent: Thursday, June 21, 2012 2:51 AM To: dovecot@dovecot.org Subject: [Dovecot] GlusterFS + Dovecot Hello, Has anyone used GlusterFS as storage file system for dovecot or any other email system..?

I've heard Dovecot complains about index corruption once in a while with glusterfs, even when not in multi-master mode. I wouldn't use it without some heavy stress testing first (with imaptest tool).
