Try "corosync-objctl runtime.totem.pg.mrp.srp.members". You should see something like: runtime.totem.pg.mrp.srp.956305584.ip=r(0) ip(176.16.0.185) runtime.totem.pg.mrp.srp.956305584.join_count=1 runtime.totem.pg.mrp.srp.956305584.status=joined runtime.totem.pg.mrp.srp.973082800.ip=r(0) ip(176.16.0.186) runtime.totem.pg.mrp.srp.973082800.join_count=1 runtime.totem.pg.mrp.srp.973082800.status=joined Note the status. If both nodes show "status=joined", corosync should be communicating OK, and the problem is at a higher level (Pacemaker), in which case check /var/log/messages for errors from e.g.: crmd, cib etc. If either node shows status=left, there's a lower level problem (network, firewall (although you ruled that out), etc.). For lower level stuff possibly try asking on the openais mailing list, which is where the corosync devs hang out: http://corosync.org/doku.php?id=support Regards, Tim -- Tim Serong <[email protected]> Senior Clustering Engineer, OPS Engineering, Novell Inc. _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
