[Dovecot] Dovecot ontop of glusterfs issue.

[Eliezer Croitoru]

Hey,

I am testing Glusterfs as a storage backend for dovecot as a LDA and 
imap server.
I have seen similar lines in the logs to these:
May 21 10:46:01 mailgw dovecot: imap(eliezer at ngtech.co.il): Warning: 
Created dotlock file's timestamp is different than current time 
(1400658105 vs 1400658361): 
/home/vmail/ngtech.co.il/eliezer/Maildir/.Mailing_lists.ceph_users/dovecot-uidlist
May 21 10:46:01 mailgw dovecot: imap(eliezer at ngtech.co.il): Error: 
Transaction log 
/home/vmail/ngtech.co.il/eliezer/Maildir/dovecot.index.log: duplicate 
transaction log sequence (2713)

The volume is mounted only by one server with ubutntu 14.04.
I have seen threads and posts about similar issue with nfs.
I want to try to debug the issue but note that with the same settings of 
the server nfs worked fine but slower.
dovecot -n output:

The glusterfs is a replicated volume constructed of two bricks which is 
mounted only on one dovecot server.
All three servers are using the same ntp pool and are synced.

Any direction is better then the state I am now.

Thanks,
Eliezer
