Anyway, I've been working on implementing a 2-node HA Xymon cluster using
LinuxHA, and probably DRBD for shared disk (I have yet to implement DRBD,
though).  The Apache and Xymon services fail over to the other node fairly
nicely, and I have successfully testing that using a shared IP to the Xymon
web page works.  It's still in the early stages of implementation and
testing, but so far it appears hold hold promise.

I'd be interesting in hearing about other HA solutions that have been
implemented (if any).  I don't recall previous mention of LinuxHA, so if no
one else has done it, I'll be glad to update the list with my progress.

I was thinking of switching it over to linux-HA though, because it takes
3-5 seconds to fail over, and this seems too slow for me

how fast does linuxHA failover?

I haven't gotten down to tuning the setup, but out of the box, LinuxHA seems to fail over in about that same 3-5 second time frame.  That's with the heartbeat going through the primary LAN interface, and just going by what crm_mon says (with a 5 second update interval).


Once I get DRBD up and running on the nodes, I'm going to do a bit more exhaustive testing and see how quickly and smoothly I get can things to fail over.  Maybe now that I've started this thread, it will give me an incentive to spend some more time on this ;-)
