What isn't working with heartbeat?
Basically it just doesn't start properly on the secondary node.
I describe all my trials and tribulations in the following thread on Linux-HA Users: http://lists.linux-ha.org/pipermail/linux-ha/2007-November/029068.html.
Looking through the archive it seems that I'm not alone and heartbeat is not stable yet.
It may be just that some help getting heartbeat working properly is all you need?
I'd love to get it. I've been chasing this for over a week now (I started this thread a few days after hitting the first problem) with no success.
I'm contemplating trying to switch to i386 to see if it'll help, but that's voodoo workaround, I don't trust a solution where the response from the coders about the problem is just "that's very weird", and I suspect that i386 might not take full advantage of the Dual Xeon 3150+8Gb memory (possibly more soon after) that I plan to have on those nodes.
If after working with it fully configured properly it still doesn't work the way you need it then I'd look at another clustering solution.
I tried the instructions in http://wiki.centos.org/HowTos/Ha-Drbd which seems to be explaining exactly the kind of configuration I want. I got DRBD working alright even before finding those instructions but the heartbeat part is the problem. The first execution of crm_mon on the first node doesn't behave according to the instructions (it takes about 3 minutes to start giving input, and then it only reports the node itself). On the secondary node it doesn't work at all.
Since all I want from it is a tiny part of its complex possibilities (just two nodes, and an active/passive configuration for now), I'd go even for setting up my own scripts though I'd MUCH rather stick to something which comes with CentOS, it would give me a feeling that it was better tested and supported.
ANY tips about anything related to that would be greatly appreciated. I'm just running out of time to set this up (customers are waiting).
Thanks,
