RE: [Linux-cluster] service state unchanged when host crashes



Hi, 

This does look like the same problem:

martin clusternode27:~$ sudo /usr/sbin/cman_tool -f nodes
Node  Sts   Inc   Joined               Name
  27   M     44   2009-10-27 14:59:33  clusternode27
  28   M     52   2009-10-27 14:59:49  clusternode28
  30   X     64                        clusternode30
       Node has not been fenced since it went down

Even though the message in syslog claims that the fencing succeeded.

Thanks for the help.

regards,
Martin

I've had this bug too using Gentoo and RHCS stable-2. After a bit of investigation I've found the bug and the solution (a small, tiny, trivial 2-line patch to fenced) I've already posted on RH bugzilla but got no response.
https://bugzilla.redhat.com/show_bug.cgi?id=512512

The patch worked out for me and cluster is in production from august.
Hope it helps.
