Anyone had success using some other clustered/HA filestore with
dovecot
who
can share their experience? (OCFS/GFS over DRBD, etc?)
My interest is more in bootstrapping a more highly available system from lower quality (commodity) components than very high end use
we use drbd with ext3 in a active/passive setup for more than 10000 mailboxes. works like a charm!
I'm not really trusting cluster filesystems and most cluster filesystems are not made for small files.
I use GlusterFS with Dovecot and it works without issues. The GlusterFS team has made huge progress since 2.0 and with the new 3.0 version they have again proved that GlusterFS can get better.

Hi Steve,
I was wondering if perhaps I might snag a copy of your glusterfs server/client configs to see what you are doing? I am interested in using it in our mail setup, but last I tried a little over a month ago I got a bunch of corrupted mails, so far I am only using for a web cluster and that seems to be working but different use case I guess.
Server part:
volume gfs-srv-ds type storage/posix option directory /mnt/glusterfs/mailstore01 end-volume
volume gfs-srv-ds-locks type features/locks option mandatory-locks off subvolumes gfs-srv-ds end-volume

Client part:

Thanks!
