Are you looking at crm_mon? log files? I created a debug output from my RA. Furthermore I had a blackbox dump. But it now turned out, that for my resource I had to change meta-data to advertise monitor action twice (one for slave, one for master) and setup op monitor role=x interval=y instead of op monitor interval=x Since that I changed it at least for this resource monitor is working as desired. At least for now. Not sure why a Master/Slave resource has to have distinct monitor actions advertised for both roles but it seems related to that. Still don't see any monitor invocations in the log but seems there is still something wrong with the log level. Thanks anyway! regards, Felix ___ Users mailing list: Users@clusterlabs.org http://clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
[ClusterLabs] Pacemaker not invoking monitor after $interval
Hello! I am currently working on a cluster setup which includes several resources with "monitor interval=XXs" set. As far as I understand this should run the monitor action on the resource agent every XX seconds. But it seems it doesn't. Actually monitor is only invoked in special condition, e.g. cleanup, start and so on, but never for a running (or stopped) resource. So it won't detect any resource failures, unless a manual action takes place. It won't update master preference either when set in the monitor action. Are there any special conditions under which the monitor will not be executed?

[ClusterLabs] Pacemaker reload Master/Slave resource
version 1.1.13-10.el7_2.2-44eb2dd Hello! I am currently developing a master/slave resource agent. So far it is working just fine, but this resource agent implements reload() and this does not work as expected when running as Master: The reload action is invoked and it succeeds returning 0. The resource is still Master and monitor will return $OCF_RUNNING_MASTER. But Pacemaker considers the instance being slave afterwards. Actually only reload is invoked, no monitor, no demote etc. I first thought that reload should possibly return $OCF_RUNNING_MASTER too but this leads to the resource failing on reload. It seems 0 is the only valid return code. I can recover the cluster state running resource $resourcename promote, which will call notify promote notify Afterwards my resource is considered Master again. After PEngine Recheck Timer (I_PE_CALC) just popped (90ms), the cluster manager will promote the resource itself. But this can lead to unexpected results, it could promote the resource on the wrong node so that both sides are actually running master, the cluster will not even notice it does not call monitor either. Is this a bug? regards, Felix trace May 20 12:58:31 cib_create_op(609):0: Sending call options: 0010, 1048576 trace May 20 12:58:31 cib_native_perform_op_delegate(384):0: Sending cib_modify message to CIB service (timeout=120s) trace May 20 12:58:31 crm_ipc_send(1175):0: Sending from client: cib_shm request id: 745 bytes: 1070 timeout:12 msg... trace May 20 12:58:31 crm_ipc_send(1188):0: Message sent, not waiting for reply to 745 from cib_shm to 1070 bytes... trace May 20 12:58:31 cib_native_perform_op_delegate(395):0: Reply: No data to dump as XML trace May 20 12:58:31 cib_native_perform_op_delegate(398):0: Async call, returning 268 trace May 20 12:58:31 do_update_resource(2274):0: Sent resource state update message: 268 for reload=0 on scst_dg_ssd trace May 20 12:58:31 cib_client_register_callback_full(606):0: Adding callback cib_rsc_callback for call 268 trace May 20 12:58:31 process_lrm_event(2374):0: Op scst_dg_ssd_reload_0 (call=449, stop-id=scst_dg_ssd:449, remaining=3): Confirmed notice May 20 12:58:31 process_lrm_event(2392):0: Operation scst_dg_ssd_reload_0: ok (node=alpha, call=449, rc=0, cib-update=268, confirmed=true) debug May 20 12:58:31 update_history_cache(196):0: Updating history for 'scst_dg_ssd' with reload op trace May 20 12:58:31 crm_ipc_read(992):0: No message from lrmd received: Resource temporarily unavailable trace May 20 12:58:31 mainloop_gio_callback(654):0: Message acquisition from lrmd[0x22b0ec0] failed: No message of desired type (-42) trace May 20 12:58:31 crm_fsa_trigger(293):0: Invoked (queue len: 0) trace May 20 12:58:31 s_crmd_fsa(159):0: FSA invoked with Cause: C_FSA_INTERNAL State: S_NOT_DC trace May 20 12:58:31 s_crmd_fsa(246):0: Exiting the FSA trace May 20 12:58:31 crm_fsa_trigger(295):0: Exited (queue len: 0) trace May 20 12:58:31 crm_ipc_read(989):0: Received cib_shm event 2108, size=183, rc=183, text: http://clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
