Just bring up the cluster with the new names and use "crm configure node delete" to remove the old names. On Mon, Oct 4, 2010 at 2:12 PM, Karl Rößmann wrote: > Hi Clusterlabs mailing list, > > I have a running cluster with three nodes. > For some reason I had to change all host names > and their

[Pacemaker] "Election Timeout" and node became the "Pending" state.

Hi, We tested complicated node trouble. An error of "Election Timeout" occurred then. * Pacemaker:pacemaker-1.0.9.1 * heartbeat-3.0.3-2.3.el5 * cluster-glue:cluster-glue-1.0.6-1.6.el5 * resource-agents-1.0.3-1.0.dev.b7a3b1973ba7 We tested it in the next procedure. Step1) Start all nodes

[Pacemaker] Patch for slow remote connections

Hi This patch solves slow responses from remote nodes. Author is Al Stone (in CC); he's not on the list as far as I know. I've tested the patch and it does do the trick. Without the patch response was ~3 seconds, while now it's ~0.3 seconds. Index: pacemaker-1.1.2+hg20100918/cib/remote.c

[Pacemaker] crm_mon SNMP function

Hi all, I use openais/pacemaker v.1.1.2 on SLES 11.1 and would like to use the SNMP function of crm_mon. But this part is documented really scanty (e.g. the part for configuring SNMP notifications is blank). I found out that there is a special MIB named linux-ha-mib but I don´t know how to use

Re: [Pacemaker] Dependency on either of two resources

Hi, a similar or related use case that we tried to solve without success: - a stretch cluster with two disk boxes - a LUN on each disk box guarded by an individual SFEX - a mirror (raid1 or clvm) that survives an outage of one disk box - the mirror should be started if at least one SFEX can be obta
