Set grace period for host fencing
by Luca 'remix_tj' Lorenzetto 15 Dec '16

15 Dec '16

Hello, i was doing some tests on how ovirt reacts to host failures. I've seen that in case of network failure an host stais in non responding state for 60 seconds before being fenced. Event log reports: Host XXX is not responding. It will stay in Connecting state for a grace period of 61 seconds and after that an attempt to fence the host will be issued. Does this value can be set to a lower/different value? I've seen that this becomes of at least 1 minute for restarting the HA-protected vms of that host. If that host, additionally, hosts also the engine, a vm (different from the engine) will start not before 6 minutes, which is a very long time.

How can I import VMWare OVA file to oVirt 4.0?

Hello oVirt guru`s! In the process of importing from OVA file (from /tmp/rhel_Vsp-4.4.0.GA-53.ova in one of hosts) VM first appears in the web console, then disappears.

Unable to change compatibility version due to hosted engine
by Renout Gerrits 15 Dec '16

15 Dec '16

Hi All, We have an environment which we want to upgrade to ovirt 4.0. This was initially installed at 3.5, then upgraded to 3.6. Problem we're facing is that for an upgrade to 4.0 a compatibility version of 3.6 is required. When changing the cluster compatibility version of the 'Default' cluster from 3.5 to 3.6 we get the error in the gui: "Cannot change cluster compatibility version when a VM is active. please shutdown all VMs in the cluster." Even when we shutdown all vm's, except for the Hosted Engine we get this error. On the hosts a 'vdsClient -s 0 list' is done which will return the HE. In the engine logs we have the following error: "2016-12-08 13:00:18,139 WARN [org.ovirt.engine.core.bll.storage.UpdateStoragePoolCommand] (default task-25) [77a50037] CanDoAction of action 'UpdateStoragePool' failed for user admin@internal. Reasons: VAR__TYPE__STORAGE__POOL,VAR__ACTION__UPDATE,$ClustersList Default,ERROR_CANNOT_UPDATE_STORAGE_POOL_COMPATIBILITY_VERSION_BIGGER_THAN_CLUSTERS" So problem would be that the HE is in the Default cluster. But how does one change the compatibility version when the HE is down? I've tried shutting down the engine, changing the version in the DB: "UPDATE vds_groups SET compatibility_version='3.6';" and starting the engine again. When I do that and try to start a VM: 2016-12-09T13:30:21.346740Z qemu-kvm: warning: CPU(s) not present in any NUMA nodes: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 2016-12-09T13:30:21.346883Z qemu-kvm: warning: All CPU(s) up to maxcpus should be described in NUMA config 2016-12-09T13:30:21.355699Z qemu-kvm: "-memory 'slots|maxmem'" is not supported by: rhel6.5.0 So that change was rolled back to compatibilty 3.5. After that we we're able to start vm's again. Please note that all hosts and HE are EL7. To me this doesn't seem like a strange set-up or upgrade path. Would it be possible to start the HE in another cluster than Default or is there a way to bypass the vdsClient list check? What is the recommended way of upgrading the HE in this case? Kind regards, Renout

dedicated gluster storage network
by Nathanaël Blanchet 15 Dec '16

15 Dec '16

Hi, I changed the previous all in one network to a dedicated gluster storage at the network level. But when doing netstat (or gluster peer status), I can see that listening connection still use the previous vlan and gluster bricks are probed on this vlan. I detached them with ovirt or manually to probe them an other time, but they are still probed on the initial ovirtmgmt vlan. What is this gluster network supposed to do in reality? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

Check your network configuration of the manager. I had the same issue and i solved by adding a secondary NIC to the manager VM in the same network as the NFS storage (172.16.8.x in your setup).

No idea, but it might be possible using affinity rules and/or HA. Changing the subject, to try to attract more relevant responses, and adding Tomer. Best, -- Didi
