Hi all,
I am trying to configure custom fencing using fence_virsh in order to test out fencing flows with my virtualized oVirt hosts. I'm getting a failure when clicking the "Test" button. Can someone help me to diagnose the problem? I have applied the following settings using engine-config:
~/ovirt-engine/bin/engine-config -s CustomVdsFenceType="xxxvirt" ~/ovirt-engine/bin/engine-config -s CustomFenceAgentMapping="xxxvirt=virsh" ~/ovirt-engine/bin/engine-config -s CustomVdsFenceOptionMapping="xxxvirt:address=ip,username=username,password=password"
(note that engine-config seems to arbitrarily limit the number of mapped options to 3. Seems like a bug to me).
Here is the log output in engine.log:

Looks like this bug:
Indeed it is. So I looked at the host to see what the failure was and I get the following messages. It looks like engine is not passing the contents of the 'Slot' UI field as the port option. This, even after I changed the param mapping like so: engine-config -s CustomVdsFenceOptionMapping="xxxvirt:address=ip,username=username,password=password,slot=port" Thread-440::DEBUG::2014-07-15 15:06:46,997::API::1165::vds::(fenceNode) fenceNode(addr=192.168.2.101,port=,agent=virsh,user=root,passwd=XXXX,action=status,secure=,options==block-cascade) Thread-440::DEBUG::2014-07-15 15:06:46,997::utils::594::root::(execCmd) /usr/sbin/fence_virsh (cwd None) Thread-440::DEBUG::2014-07-15 15:06:47,035::utils::614::root::(execCmd) FAILED: <err> = "WARNING:root:Parse error: Ignoring unknown option '=block-cascade'\n\nERROR:root:Failed: You have to enter plug number or machine identification\n\nERROR:root:Please use '-h' for usage\n\n"; <rc> = 1 Thread-440::DEBUG::2014-07-15 15:06:47,035::API::1152::vds::(fence) rc 1 inp agent=fence_virsh ipaddr=192.168.2.101 login=root action=status passwd=XXXX =block-cascade out [] err ["WARNING:root:Parse error: Ignoring unknown option '=block-cascade'", '', 'ERROR:root:Failed: You have to enter plug number or machine identification', '', "ERROR:root:Please use '-h' for usage", ''] Thread-440::DEBUG::2014-07-15 15:06:47,035::API::1188::vds::(fenceNode) rc 1 in agent=fence_virsh ipaddr=192.168.2.101 login=root action=status passwd=XXXX =block-cascade out [] err ["WARNING:root:Parse error: Ignoring unknown option '=block-cascade'", '', 'ERROR:root:Failed: You have to enter plug number or machine identification', '', "ERROR:root:Please use '-h' for usage", '']
