We tested 16 node constitution (15+1). We carried out the next procedure.
Step1) Start 16 nodes. Step2) Send cib after a DC node was decided. An error occurs by the update of the attribute of pingd after Probe processing was over. ---------------------------------------------------------------------------------------------------------------------------------------- Jun 14 10:58:03 hb0102 pingd: [2465]: info: ping_read: Retrying... Jun 14 10:58:13 hb0102 attrd: [2155]: WARN: attrd_cib_callback: Update 337 for default_ping_set=1600 failed: Remote node did not respond Jun 14 10:58:13 hb0102 attrd: [2155]: WARN: attrd_cib_callback: Update 340 for default_ping_set=1600 failed: Remote node did not respond Jun 14 10:58:13 hb0102 attrd: [2155]: WARN: attrd_cib_callback: Update 343 for default_ping_set=1600 failed: Remote node did not respond Jun 14 10:58:13 hb0102 attrd: [2155]: WARN: attrd_cib_callback: Update 346 for default_ping_set=1600 failed: Remote node did not respond Jun 14 10:58:13 hb0102 attrd: [2155]: WARN: attrd_cib_callback: Update 349 for default_ping_set=1600 failed: Remote node did not respond ---------------------------------------------------------------------------------------------------------------------------------------- In the middle of this error, I carried out a cibadmin(-Q optin) command, but time-out occurred. In addition, cib of the DC node seemed to move by the top command very busily. In addition, a communication error with cib occurs in the DC node, and crmd reboots. ---------------------------------------------------------------------------------------------------------------------------------------- Jun 14 10:58:09 hb0101 attrd: [2278]: WARN: xmlfromIPC: No message received in the required interval (120s) Jun 14 10:58:09 hb0101 attrd: [2278]: info: attrd_perform_update: Sent update -41: default_ping_set=1600 (snip) Jun 14 10:59:07 hb0101 crmd: [2280]: info: do_exit: [crmd] stopped (2) Jun 14 10:59:07 hb0101 corosync[2269]: [pcmk ] plugin.c:858 info: pcmk_ipc_exit: Client crmd (conn=0x106a2bf0, async-conn=0x106a2bf0) left Jun 14 10:59:08 hb0101 corosync[2269]: [pcmk ] plugin.c:481 ERROR: pcmk_wait_dispatch: Child process crmd exited (pid=2280, rc=2) Jun 14 10:59:08 hb0101 corosync[2269]: [pcmk ] plugin.c:498 notice: pcmk_wait_dispatch: Respawning failed child process: crmd Jun 14 10:59:08 hb0101 corosync[2269]: [pcmk ] utils.c:131 info: spawn_child: Forked child 2680 for process crmd Jun 14 10:59:08 hb0101 crmd: [2680]: info: Invoked: /usr/lib64/heartbeat/crmd Jun 14 10:59:08 hb0101 crmd: [2680]: info: main: CRM Hg Version: 9f04fa88cfd3da553e977cc79983d1c494c8b502 Jun 14 10:59:08 hb0101 crmd: [2680]: info: crmd_init: Starting crmd Jun 14 10:59:08 hb0101 crmd: [2680]: info: G_main_add_SignalHandler: Added signal handler for signal 17 ---------------------------------------------------------------------------------------------------------------------------------------- There seems to be a problem in cib of the DC node somehow or other. We hope that an attribute change is completed in 16 nodes definitely. * Is this phenomenon a limit of the current cib process? The log attached it to next Bugzilla. * http://developerbugs.linux-foundation.org/show_bug.cgi?id=2443 Best Regards, Hideo Yamauchi. _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker
