Greetings, I am currently researching ways to implement a somewhat advanced cluster scheme, and I can't seem to find any evidence of anyone else attempting a similar setup. I'm curious if what I'm looking to do is even possible with heartbeat.
The general idea is to have a cluster of 7 servers, sharing 5 sets of resources - so, 5 active servers and a 'pool' of 2 idle servers. The cluster would be set up in such a way that if any of the 5 active servers is put out of commission, one of the idle servers can take up its resources, and, once the out-of-commission server is repaired, it joins the idle pool.
Conversely, no active server must ever take more than one set of resources - that is to say, if Server-001 and Server-002 are active, and Server-002 dies, Server-001 should ignore this fact and let one of the idle servers worry about it. For the sake of completeness, the resources involved would be IP addresses and remotely-mounted disks (NFS/iSCSI), one each per 'set of resources'. So, first off, does this plan make any sense? And more importantly, is this something that could be accomplished with heartbeat? Any suggestions or advice would be greatly appreciated. Many thanks, J.
