[Users] Host status non-responsding
Hi, While performing some operations (vdsm restart and other operations to debug SSL settings on the host) , my host goes to non-responding state. Now it has happened for the third time. For the previous two times I did a engine-cleanup and did a engine-setup to resolve this issue. Is there some other way ... m guessing removing some host entry from database or something to recover faster. On a non-responding host I can't put it to maintenance mode because it says it has running Vms on it... also I cant remove it and add it again, so basically my host is in a state of limbo where I cant perform any operation on it. Is there any other way to recover from such condition other that preforming a engine cleanup and engine-setup again ? -- Regards, Rahul === ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Well , if you stop vdsm service , your host is in non-responding state and that's OK Now it has happened for the third time. For the previous two times I did a engine-cleanup and did a engine-setup to resolve this issue. Is there some other way ... m guessing If you can define Power Management on that hots, your host will be automatically rebooted in such a case removing some host entry from database or something to recover faster. On a non-responding host I can't put it to maintenance mode because it says it has running Vms on it... also I cant remove it So, it is the only running host in your system. If you define one more host and run it you can send a non-responding host to maintainance since HA VMs will migrate to the other host and add it again, so basically my host is in a state of limbo where I cant perform any operation on it.

[Users] high availability via fencing
Hello, I'm testing ovirt for potential deployment and one of the metrics for its success relies on the high availability feature. In my research on this feature, I found scattered documentation indicating that fencing is a prerequisite. On my test hardware, I don't have any LOM/IPMI but I see that APC managed PDUs are supported, which I do have. The problem is when I try to configure Power Management to use the apc type, I get this error: Test Failed, Host Status is: unknown. The fence-agent script reported the following error: Failed: You have to enter plug number Please use '-h' for usage ovirt-engine/engine.log tells me: 2012-04-20 11:32:44,595 INFO [org.ovirt.engine.core.bll.FencingExecutor] (http--0.0.0.0-8443-5) Executing Status Power Management command, Proxy Host:heilig, Agent:apc, Target Host:, Management IP:134.174.x.x, User:ovirt, Options:port=22,secure=true,slot=1 2012-04-20 11:32:44,598 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.FenceVdsVDSCommand] (http--0.0.0.0-8443-5) START, FenceVdsVDSCommand(vdsId = 6de5e3fa-8a33-11e1-b3f9-003048c85226, targetVdsId = 60087c5e-8a3b-11e1-b15d-003048c85226, action = Status, ip = 134.174.x.x, port = , type = apc, user = ovirt, password = **, options = 'port=22,secure=true,slot=1'), log id: 57f86a56 2012-04-20 11:32:44,696 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.FenceVdsVDSCommand] (http--0.0.0.0-8443-5) FINISH, FenceVdsVDSCommand, return: Test Failed, Host Status is: unknown. The fence-agent script reported the following error: Failed: You have to enter plug number Please use '-h' for usage I've tried to add port=1 to the Options field but that seems to have no effect. Any ideas? Is there any way to configure a dumb power management / fencing configuration for testing? Cheers, Ian ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
