This was fixed in a checkin on the 16th December - and works for me with current CVS. I am still seeing this with the RPMs built yesterday, Monday January 10. Missed a corner case, sorry Checking in membership.c; /cvs/cluster/cluster/cman-kernel/src/membership.c,v <-- membership.c new revision: 1.47; previous revision: 1.46 done Still doesn't appear to be working. These messages are from link-10; ran 'cman_tool leave remove' on link-11 and then link-12. 15 seconds later activity is blocked. CMAN: removing node link-12 from the cluster : Removed Feb 10 11:03:16 link-10 kernel: CMAN: Node link-12 is leaving the cluster, Removed Feb 10 11:03:16 link-10 kernel: CMAN: removing node link-12 from the cluster : Removed CMAN: removing node link-11 from the cluster : Removed Feb 10 11:03:41 link-10 kernel: CMAN: Node link-11 is leaving the cluster, Removed Feb 10 11:03:41 link-10 kernel: CMAN: removing node link-11 from the cluster : Removed CMAN: quorum lost, blocking activity Feb 10 11:03:56 link-10 kernel: CMAN: quorum lost, blocking activity Node Votes Exp Sts Name 1 1 3 M link-10 2 1 3 X link-11 3 1 3 X link-12 Protocol version: 5.0.1 Config version: 2 Cluster name: MILTON Cluster ID: 4812 Membership state: Cluster-Member Nodes: 1 Expected_votes: 3 Total_votes: 1 Quorum: 2 Activity blocked Active subsystems: 9 Node addresses: 192.168.44.160 Service Name GID LID State Code Fence Domain: "default" 1 2 run - [1] DLM Lock Space: "clvmd" 2 3 run - [1] DLM Lock Space: "data1" 3 4 run - [1] DLM Lock Space: "data2" 5 6 run - [1] GFS Mount Group: "data1" 4 5 run - [1] GFS Mount Group: "data2" 6 7 run - [1] You've got 2 GFS filesystems mounted, it shouldn't even start shutdown on that node. Did you get a failure message from cman_tool leave? <puzzled> ? Yes, I have 2 filesystems mounted on link-10. I'm not trying to shut down cman on link-10, however. The expectation is that since the other two nodes left with "remove" the last node would remain quorate and not go into "Activity Blocked" mode. Apologies, I read that message just before I left and thought it referred to a different bz. Looks like a bit more patience would have helped me when testing the previous fix too. It seems that the transition timer was being set for a single-node transition when it shouldn't have. So after the node had settled down nicely and self-quorate, the timer kicked in 15 seconds later and spoiled it all. This checkin should fix it, and it will also get rid of the duplicate leave message too.
