Just wanted to post a quick update in regards to the QMT ISP Array I've
been working on setting up for the past while. I initially followed
Jake's video and got some tips from both and him and Schubes regarding a
few questions I had...anyways, I've actually setup my back-end DB
servers several times now, each time trying something a little bit
different, and I'm liking the latest incarnation.
Decided I'd venture into the unknown and try out a "cluster-aware" file
system instead of using ext3/4 for my mailstore. Ended up checking out
OCFS2, and I've liked what I've seen so far. Also decided to try out
NFS4 (which didn't come without some initial issues, but alas its
working). So I have 2 Cent 5.7 boxes running OCFS2 over DRBD8.3, which
is then exported over NFS4 on both boxes, then I'm using heartbeat to
control the IP address assignment.
The vpopmail & roundcubemail DB's are being replicated between the two,
and I've setup a test front-end machine which accesses those databases
and mounts the NFS4 export (which contains my qmail config, squirrelmail
data, and I'm working on getting the rcm stuff on there as well). I'm
just working on tightening the firewall a bit, then they should be ready
to take down to the data center and get hooked up and begin testing.
Well that's about it. I'm thinking if all goes well with testing I may
do a little write up for the wiki in case any other have any interest in
setting up a similar system. Thanks again for everyone that's answered
my incredibly long emails and never-ending questions :-)
