How do you manage your Cyrus installations highly-available?
Check the archives. There have been many discussions regarding this.
I though a minimal example could be like below:
internet
|
server1 ----- server2
There would be Heartbeat/Pacemaker running on both servers. Its role
would be:
- assign "Cyrus IP" to a given server,
- start Cyrus where "Cyrus IP" is up.
Still, we need to have Cyrus database, mail storage accessible for both
servers. I though using glusterfs for it would be a good idea (assuming
Cyrus only runs on one of the servers at a given time).
We use a similar setup with standard ext3 file systems that are mounted and unmounted as needed; in our case that's done by the RHEL 3 Cluster Suite. That's been working great for almost 6 years now.
