Description David Teigland 2009-06-04 13:14:26 EDT
Description of problem:


Nate found this bug running revolver on 5 nodes, when two or three nodes were killed at the same time.

The groupd logs show that cpg delivers the confchg's for the killed nodes in different orders.

The first time, nodes 1,3,4 were killed, leaving 2,5.
nodeid 2 got confchg order: 4,3,1
nodeid 5 got confchg order: 1,3,4

The second time, nodes 2,5 were killed, leaving 1,3,4.
1 got 2,5
3 got 5,2
4 got 5,2

Comment 1 Nate Straz 2009-06-04 16:09:54 EDT
The result of this bug is that after a cluster failure, all cluster services will be stuck because recovery can not complete.  The entire cluster needs to be rebooted to recover from this scenario.
Comment 2 Steven Dake 2009-06-04 17:32:19 EDT
changed to 5.4, all archs, urgent, urgent.
Comment 3 Steven Dake 2009-06-04 17:33:34 EDT
one liner patch in testing now, assuming it fixes the problem this is a serious regression in the 5.4 version.
Comment 4 Steven Dake 2009-06-05 12:45:56 EDT
5.4 regression.
