Hi Honza attached log from another cluster on primary node grep Library corosync-fico-mail-20140221.logFeb 21 04:41:33 [27122] fico-mail crmd: error: pcmk_cpg_dispatch: Connection to the CPG API failed: Library error (2) Feb 21 04:41:33 [27120] fico-mail attrd: error: pcmk_cpg_dispatch: Connection to the CPG API failed: Library error (2) Feb 21 04:41:33 [27118] fico-mail stonith-ng: error: pcmk_cpg_dispatch: Connection to the CPG API failed: Library error (2) Feb 21 04:41:33 [27117] fico-mail cib: error: pcmk_cpg_dispatch: Connection to the CPG API failed: Library error (2) Feb 21 04:41:35 [27111] fico-mail pacemakerd: info: crm_cs_flush: Sent 0 CPG messages (1 remaining, last=10): Library error (2) Feb 21 04:41:35 [27111] fico-mail pacemakerd: error: pcmk_cpg_dispatch: Connection to the CPG API failed: Library error (2)
same story on secondary node egrep "pause|scheduled" corosync-nespolo-ext-20140221.logFeb 21 04:41:27 corosync [TOTEM ] Process pause detected for 5011 ms, flushing membership messages. Feb 21 04:41:27 corosync [MAIN ] Corosync main process was not scheduled for 8759.2314 ms (threshold is 2400.0000 ms). Consider token timeout increase. Feb 21 04:41:38 corosync [TOTEM ] Process pause detected for 1955 ms, flushing membership messages.
secondary node is on an old and slow host used for backup and it's not easy to solve perfomance problem
