I'd like to point out (to Lars) that i also (like Martin did) see many syslog messages in SLES11 SP2 (+ Updates) when using clvmd: I created a physical volume in a 5-node-cluster, and one host logged: Aug 21 14:08:38 o1 clvmd[30725]: Got new connection on fd 5 Aug 21 14:08:38 o1 clvmd[30725]: Read on local socket 5, len = 31 Aug 21 14:08:38 o1 clvmd[30725]: check_all_clvmds_running Aug 21 14:08:38 o1 clvmd[30725]: down_callback. node 537072812, state = 3 Aug 21 14:08:38 o1 clvmd[30725]: down_callback. node 587404460, state = 3 Aug 21 14:08:38 o1 clvmd[30725]: down_callback. node 520295596, state = 3 Aug 21 14:08:38 o1 clvmd[30725]: down_callback. node 553850028, state = 3 Aug 21 14:08:38 o1 clvmd[30725]: down_callback. node 570627244, state = 3 Aug 21 14:08:38 o1 clvmd[30725]: creating pipe, [12, 13] Aug 21 14:08:38 o1 clvmd[30725]: Creating pre&post thread Aug 21 14:08:38 o1 clvmd[30725]: Created pre&post thread, state = 0 Aug 21 14:08:38 o1 clvmd[30725]: in sub thread: client = 0x6bee00 Aug 21 14:08:38 o1 clvmd[30725]: Sub thread ready for work.

Maybe I'm expecting too much, but isn't it possible to simply log "Telling other nodes that PV blabla is being created"? lvm2-2.02.84-3.33.1 lvm2-clvm-2.02.84-3.25.30 cmirrord-2.02.84-0.7.37 Regards, Ulrich _______________________________________________ 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
