cman: Fix inconsistent state if a node leaves/joins quickly
I am still able to get the cluster in an inconsistent state after running "service cman restart" on one node.
[nstraz@z ~]$ for i in z{1,2,3,4}; do echo "$i:"; qarsh -l root $i cman_tool nodes; done

Given that bz#472786 has been verified as fixed, and it's the same bug, are we sure that the Z-stream package has that patch included ? Yes, I talked with nate and he is using cman-2.0.98-1.el5_3.7 which I verified contains the patch:
- if (node->state == NODESTATE_DEAD) {
+ if (node->state == NODESTATE_DEAD || node->state == NODESTATE_LEAVING) {
I reinstalled the systems and tried the test again and it passed this time around. Last time I was working with 3, 4, and 5 node clusters, perhaps I didn't have all nodes updated correctly. Calling this verified now. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
