How do you manage your Cyrus installations highly-available?
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).
However, something doesn't work with it very well when Cyrus data is on a
glusterfs mount point (if I move it to a local disk, everything works well):
