A probe is run on every node to find out in which state the resource is there before doing anything to the resource.

Which heartbeat version do you run?

[Linux-HA] Assymetric Clustering
Hi, I'm quite new to clustering and HeartBeat, but as far as I know, a very nice packages. Well, here is my problem, I'm willing to setup a cluster for an small enterprise that will have several services located in virtual machines, to make it simpler, let's say we have four nodes in the cluster, in two nodes will run service A and in the other two nodes will run service B. I would like to make it in one cluster and not in two miniclusters because of later migration posibilities, easier administration,etc. I'm working with Ubuntu server 8.10 , with heartbeat-2 distrib packages. Now, Ive setup the first two nodes, with service A with no problem , service A is lsb, in my test is simply an apt-proxy with a virtual IP and a drbd for shared storage. After learning how to do it, it works flawesly, crm_verify didn't complain , all just fine. I've setup location rules to only let service A to run in these two nodes Then I decided to add the other two nodes to the cluster, to continue with service B, and here is the problem, even if these new nodes aren't allowed to run service A, it seems that the CRM tells the LRM to monitor service A on these nodes, as apt-proxy and drbd are not even installed there, it complains with errors with drbd, and failed on apt-proxy. AM I missing something here, or those test shouldn't be there, as location forbids those nodes for running this services.:,( I would really appreciate any light you can bring on this, as Im struggling with it for the last days. thanx in advance, and my apologies if my english is not as good as it should! :-D -- View this message in context: http://www.nabble.com/Assymetric-Clustering-tp23144951p23144951.html Sent from the Linux-HA mailing list archive at Nabble.com. ___ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
