Hi guys,
I'm looking at the possibility of running a pair of servers with Dovecot LDA/imap/pop3 using internal drives with DRBD and GFS (or other clustered FS) for the mail storage and ext3 for the root drive.
I'm currently using maildrop for delivery and Dovecot imap/pop3 with the stores over NFS. I'm looking for better performance but still keeping the HA element I have now with shared storage over NFS.
Has anyone had experience with a setup like the one I'm suggesting? What was performance like with Dovecot using GFS?
Thanks Guy
i tested DRBD with ocfs which works nice, also did tests with linux ha
perhaps this helps

cant get GFS run on ubuntu ( maybe my fault )
didnt test dovecot and postfix setup implemented in the ha-lb-cluster yet ( but ocfs was reported to work nice with dovecot deliver as far i remember), i used only apache http service for testing, but that worked nice in a vmware testing field with 4 servers ( 2 redundant loadbalancer and 2 Ha Servers )
