I don't see anything unusual in the config except that pacemaker mode is also enabled. This means that the cluster is providing signal for sbd even when the storage device is down, for example: 883 ? SL 0:00 sbd: inquisitor 892 ? SL 0:00 \_ sbd: watcher: /dev/vdb1 - slot: 0 - uuid: 18b958fa-fdae-455a-aa9d-a204a6eed04b 893 ? SL 0:00 \_ sbd: watcher: Pacemaker 894 ? SL 0:00 \_ sbd: watcher: Cluster You can strace different sbd processes to see what they are doing at any point. Easy way to test if watchdog is working is to pause all sbd processes, for example: # pkill -STOP sbd For me this causes a node reset after 5 seconds as defined by: SBD_WATCHDOG_TIMEOUT=5 -- Valentin _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
