Hi, I am setting up a cluster using: Linux kernel 3.6.6 Corosync 2.1.0 DLM 4.0.0 CLVMD 2.02.98 Pacemaker 1.1.8 DRBD 8.3.13 Now I have stuck on the 'clean shutdown of a node' scenario. It goes like that: - resources using the shared storage are properly stopped by Pacemaker. - DRBD is cleanly demoted and unconfigured by Pacemaker - Pacemaker cleanly exits - CLVMD is stopped. – dlm_controld is stopped – corosync is being stopped and at this point the node is fenced (rebooted) by the dlm_controld on the other node. I would expect it continue with a clean shutdown. Any idea how to debug/fix it? Is this '541 cpg_dispatch error 9' the problem? Logs from the node being shut down (log file system mounted with the 'sync' option, syslog shutdown delayed as much as possible): Kernel: Nov 19 09:49:40 dev1n2 kernel: : [ 542.049407] block drbd0: worker terminated Nov 19 09:49:40 dev1n2 kernel: : [ 542.049412] block drbd0: Terminating drbd0_worker Nov 19 09:49:43 dev1n2 kernel: : [ 544.934390] dlm: clvmd: leaving the lockspace group...
