Description Derek Anderson 2004-09-22 15:35:39 EDT
Description of problem:
Similar to bug #132989, but for the fence_tool.

I'm in a state where a fence operation is failing, so the fence domain
service is in the "recover" state.  Attempt to do a "fence_tool leave"
in this state is not going to work (and doesn't, which is fine). 
However, the tool returns zero and reports no error.

[root@tng3-1 cluster]# cat /proc/cluster/services
Service          Name                              GID LID State     Code
Fence Domain:    "default"                           1   2 recover 2 -
[1 4 2 5]

[root@tng3-1 cluster]# fence_tool leave
[root@tng3-1 cluster]# echo $?
[root@tng3-1 cluster]# cat /proc/cluster/services
Service          Name                              GID LID State     Code
Fence Domain:    "default"                           1   2 recover 2 -
[1 4 2 5]

[root@tng3-1 cluster]#

Version-Release number of selected component (if applicable):
[root@tng3-1 cluster]# fence_tool -V
fence_tool DEVEL.1095793252 (built Sep 21 2004 14:03:23)

How reproducible:

Steps to Reproduce:
1. Put the fence domain service in 'recover' state
2. Run 'fence_tool leave'
Actual results:
Return code 0, no error reported.

Expected results:
Non-0 return code. Error reported.

fence_tool leave just does kill(pid, SIGTERM).  I can't think
of a nice way off hand to check if fenced exits or not.  I
believe it /will/ exit in response to the delivered signal
once it's done with recovery.  In that sense, it's successful
even if fenced doesn't exit immediately.  Will think about this
a bit more, any ideas are welcome.

Same issue as ccs_update...

Is there some sort of ping you could give the fence daemon that responds by 
saying "aliving" or "shuting down"?  Perhaps this is over-engineering the

Updating version to the right level in the defects.  Sorry for the storm.
