Description Alan Conway 2012-05-11 15:02:10 UTC

Description of problem:

If you set FENCE_JOIN=no in sysconfig/cman then the node should not wait on fencing. However if you do this, start a cluster and then reboot a node running a relocatable service, the system hangs. Error logs show it is waiting on a fencing operation.

Version-Release number of selected component (if applicable): RHEL 6


How reproducible: 100%


Steps to Reproduce:
1. Configure a cluster with FENCE_JOIN=no and a relocatable service.
2. Reboot the node where the relocatable service is running
  
Actual results:

The service never gets relocated, log files indicate waiting on a fencing operation.

Expected results:

Service relocates, cluster functions normally.

Unit test results:

Add:

DLM_CONTROLD_OPTS="-f 0 -q 0 -r 1"

to /etc/sysconfig/cman

service cman start (doesn´t matter how many nodes)

[root@rhel6-node2 ~]# dlm_tool dump
[snip]
1337082738 set protocol 1

(for -r 1)

ps ax |grep dlm_controld
19330 ?        Ssl    0:00 dlm_controld -f 0 -q 0 -r 1
