Hi Jan, yes, one simple resource is enough, the sbd resource ist just for monitoring ( as far as I understand ). You should see a message when starting openais : sles11sp11:~ # rcopenais start Starting OpenAIS/Corosync daemon (corosync): Starting SBD - starting... OK SBD is started before any resource comes up. Cheers, Martin -- I would rather be exposed to the inconveniences attending too much liberty, than those attending too small a degree of it. _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
