Re: [ovirt-devel] Custom fencing with virsh_fence

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: 2014-07-15 11:43:34,813 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (http--0.0.0.0-8080-1) Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: Host centennial from cluster block was chosen as a proxy to execute Status command on Host cascade. 2014-07-15 11:43:34,813 INFO [org.ovirt.engine.core.bll.FenceExecutor] (http--0.0.0.0-8080-1) Using Host centennial from cluster block as proxy to execute Status command on Host 2014-07-15 11:43:34,815 INFO [org.ovirt.engine.core.bll.FenceExecutor] (http--0.0.0.0-8080-1) Executing <Status> Power Management command, Proxy Host:centennial, Agent:virsh, Target Host:, Management IP:192.168.2.101, User:root, Options: 2014-07-15 11:43:34,816 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.FenceVdsVDSCommand] (http--0.0.0.0-8080-1) START, FenceVdsVDSCommand(HostName = centennial, HostId = a34f7dbc-dd99-4831-a1a9-54c411080ec1, targetVdsId = b6b9d480-e20f-411a-9b9c-883fac32a4e5, action = Status, ip = 192.168.2.101, port = , type = virsh, user = root, password = ******, options = ''), log id: 24f33bda 2014-07-15 11:43:34,875 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.FenceVdsVDSCommand] (http--0.0.0.0-8080-1) Failed in FenceVdsVDS method, for vds: centennial; host: 192.168.2.103 2014-07-15 11:43:34,876 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.FenceVdsVDSCommand] (http--0.0.0.0-8080-1) Command FenceVdsVDSCommand(HostName = centennial, HostId = a34f7dbc-dd99-4831-a1a9-54c411080ec1, targetVdsId = b6b9d480-e20f-411a-9b9c-883fac32a4e5, action = Status, ip = 192.168.2.101, port = , type = virsh, user = root, password = ******, options = '') execution failed.
