[hobbit] HA solutions

[Clark, Sean]

I have it running with Conga/Ricci/lucci redhat-cluster and a 3510
shared disk array.
[2 node with shared IP]
 
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 know there was a thread on this a while back, and if I recall, there
was mention that the 4.3.0 line would have features for HA.

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.
