Storage Domain High Latency
by Alan Griffiths 25 Oct '16

25 Oct '16

Hi, One of my hosts is periodically reporting high latency to a storage domain (FC). There is almost no load on the SAN so the issue must be either fault, mis-configuration or internal ovirt issue. Can anyone enlighten me on how ovirt/vdsm goes about calculating the storage latency? As I'm struggling to find anything in the logs. Thanks, Alan

Host keeps disconnecting
by Chris Cowley 25 Oct '16

25 Oct '16

Hello all I am trying out ovirt 4 on a single host using the hosted engine. All storage is on the same machine, with NFS3 in the middle. Regularly the host disconnects from the engine - although all the VMs continue working happily. I can re-activate it immediately and it will come online happily, I can then manipulate VMs to my hearts content for a few minutes until it disconnects again and I have to re-activate it. First, am I being stupid trying to run this on a single node? Am I obliged to at least break out the storage in to a seperate node/NAS Second, assuming this is technically possible, where should I be looking for clues? vdsm.log <https://drive.google.com/a/klaxoon.com/file/d/0B1WTcLeiwXQ2emhDQURjU25rYm8/…>

Host in error state
by knarra 25 Oct '16

25 Oct '16

Hi All, I am currently using ovirt master branch, having hosted-engine setup with glusterfs as the storage domain. I launched some vms and try to start them. VMs fails to start on two other hosts in the cluster and both of them go into error state. why does the hosts go into error state ? I see the following error in the vdsm logs on why the vm start process fails. 2016-10-25 12:13:37,320 ERROR (Thread-301489) [virt.vm] vmId=`0b84e276-3375-46e8-8f5f-3e0ccee82f95`::The vm start process failed (vm:582) Traceback (most recent call last): File "/usr/share/vdsm/virt/vm.py", line 523, in _startUnderlyingVm self._run() File "/usr/share/vdsm/virt/vm.py", line 1855, in _run domxml = hooks.before_vm_start(self._buildDomainXML(), File "/usr/share/vdsm/virt/vm.py", line 1555, in _buildDomainXML self._appendDevices(domxml) File "/usr/share/vdsm/virt/vm.py", line 1502, in _appendDevices deviceXML = dev.getXML().toxml(encoding='utf-8') File "/usr/share/vdsm/virt/vmdevices/storage.py", line 422, in getXML self._validate() File "/usr/share/vdsm/virt/vmdevices/storage.py", line 491, in _validate raise ValueError("Network disk without hosts") ValueError: Network disk without hosts seeing following error in the events tab "Host hosted_engine2 will be switched to Error status for 30 minutes because it failed to run a VM." seeing following error in the engine logs. 2016-10-25 06:44:36,912 INFO [org.ovirt.engine.core.vdsbroker.FailedToRunVmVDSCommand] (org.ovirt.thread.pool-6-thread-1) [20bafb6a] START, FailedToRunVmVDSCommand(HostName = hosted_engine2, FailedToRunVmVDSCommandParameters:{runAsync='true', hostId='fcf264de-6f03-4835-8c26-6927417d848b'}), log id: 5b369412 2016-10-25 06:44:36,920 INFO [org.ovirt.engine.core.vdsbroker.SetVdsStatusVDSCommand] (org.ovirt.thread.pool-6-thread-1) [20bafb6a] START, SetVdsStatusVDSCommand(HostName = hosted_engine2, SetVdsStatusVDSCommandParameters:{runAsync='true', hostId='fcf264de-6f03-4835-8c26-6927417d848b', status='Error', nonOperationalReason='NONE', stopSpmFailur eLogged='false', maintenanceReason='null'}), log id: 3ae9ae50 2016-10-25 06:44:36,927 INFO [org.ovirt.engine.core.vdsbroker.SetVdsStatusVDSCommand] (org.ovirt.thread.pool-6-thread-1) [20bafb6a] FINISH, SetVdsStatusVDSCommand, log id: 3ae9ae50 2016-10-25 06:44:36,934 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (org.ovirt.thread.pool-6-thread-1) [20bafb6a] Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: Host hosted_engine2 will be switched to Error status for 30 minutes because it failed to run a VM. 2016-10-25 06:44:36,934 INFO [org.ovirt.engine.core.vdsbroker.VdsManager] (org.ovirt.thread.pool-6-thread-1) [20bafb6a] Vds 'hosted_engine2' moved to Error mode after 3 att empts.

ovirt 3.6.7 and gluster 3.7.14
by Luiz Claudio Prazeres Goncalves 25 Oct '16

25 Oct '16

Hi, it seems the ovirt-3.6-dependencies.repo is pointing the yum repo to http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/epel-$re… and http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/epel-$re…, however the "LATEST" is now pointing to gluster 3.8.x and not to 3.7.x anymore. So, in order to fix it I was forced to manually adjust the yum repo paths as you can see below. Is this procedure correct? I would say yes, but it's always good to double check :) Also, It's currently running centos 7.2 + ovirt 3.6.6 + gluster 3.7.11 (client) and I'm planning to upgrade to ovirt 3.6.7 and gluster 3.7.14 (client). The oVirt Cluster is running on top of an external gluster replica 3 cluster, hosting the engine storage domain and vms storage domain, running the version 3.7.11 which I'm also planning to move to 3.7.14 as well. I'm using XFS and not ZFS, which seems to have issues with gluster 3.7.13 Is this upgrade safe and recommended?

Hi, I'm trying to import a VM from VMware. On the "Import Virtual Machine(s)" screen, my VCenter username is not accepted, because "Name can only contain 'A-Z', 'a-z', '0-9', '_' or '-' characters" and it contains a '.', which should be perfectly fine. Now what? Regards, Martijn.

Non responsive vms, how to reconnect hosts
by andreas.ewert＠cbc.de 24 Oct '16

24 Oct '16

Hi there, currently our vms are in a non responsive state. Due fibre channel storage problems every machine is tagged by a question mark. Datacenter is in non operational mode. Good news is that the machines are running. I verrified by „virsh list“ on the hypervisors. I know if I reboot the hypervisors then the problem will be solved. But is there any other way to connect the hypervisor hosts to the datacenter? Now storage problems are over and I already tried to restart the vdsm daemon … but no success. Do I really need to reboot the hosts? OS Version of ovirt Hosts: Centos7 DataCenter runs with version 3.5 With best regards Andreas
