hi, I have a problem with ovirt 3.6. When I click on the button "run" to start vm, it not start and terminate immediatly. This is the error in the admin portale: VM ubuexp is down with error.

Hi Nick, Try running "ls -l /rhev/data-center/00000001-0001-0001-0001-00000000037d/88dfff37-4ad5-446c-a957-1cf67829c9a6/images/da93350c-8926-42bf-99fa-8a7aca043fcd/22e7803d-e266-4e3e-ae34-0181f8acef8b" and check the ownership of the file. It should be owned by vdsm:kvm (or user and group 36:36 I think) Another thing to check would be that the parent directories are accessible. Try running "sudo -s /bin/bash vdsm" and then "cd /rhev/data-center/00000001-0001-0001-0001-00000000037d/88dfff37-4ad5-446c-a957-1cf67829c9a6/images" to make sure you can access all the parent folders. If you can, try creating a temp file ("echo hello >hello") in that same directory to make sure that the iSCSI mount hasn't gone read only. If none of that helps, I'd say take a look at the output of vgdisplay to make sure that the volume group still has free physical extents (Free PE/Size near the bottom) If you are using thin provisioning that might be an issue. This is all based on the issue being disk permission errors. It might be an error with the libvirt authentication, but I have no idea how to diagnose that.

adding glusterfs to ovirt
by Fabrice Bacchella 18 Apr '16

18 Apr '16

I installed a oVirt stack without glusterfs. Now I want to add it. So I configured a cluster to be a gluster-enabled one. Now i want to add a gluster volume to it. That went fine until I click Ok at the "New Volume" dialog, the answer was : Error while executing action Create Gluster Volume: Unexpected exception I the log, I saw : 2016-04-13 16:45:53,573 INFO [org.ovirt.engine.core.vdsbroker.gluster.GlusterTasksListVDSCommand] (DefaultQuartzScheduler_Worker-84) [5303bffb] FINISH, GlusterTasksListVDSCommand, log id: 2e5a7991 2016-04-13 16:45:53,573 ERROR [org.ovirt.engine.core.bll.gluster.GlusterTasksSyncJob] (DefaultQuartzScheduler_Worker-84) [5303bffb] Error updating tasks from CLI: org.ovirt.engine.core.common.errors.EngineException: EngineException: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSErrorException: VDSGenericException: VDSErrorException: Failed to GlusterTasksListVDS, error = The method does not exist / is not available., code = -32601 (Failed with error unexpected and code 16) at org.ovirt.engine.core.bll.VdsHandler.handleVdsResult(VdsHandler.java:112) [bll.jar:] at org.ovirt.engine.core.bll.VDSBrokerFrontendImpl.RunVdsCommand(VDSBrokerFrontendImpl.java:33) [bll.jar:] at org.ovirt.engine.core.bll.gluster.tasks.GlusterTasksService.runVdsCommand(GlusterTasksService.java:64) [bll.jar:] at org.ovirt.engine.core.bll.gluster.tasks.GlusterTasksService.getTaskListForCluster(GlusterTasksService.java:32) [bll.jar:] at org.ovirt.engine.core.bll.gluster.GlusterTasksSyncJob.updateGlusterAsyncTasks(GlusterTasksSyncJob.java:87) [bll.jar:] at sun.reflect.GeneratedMethodAccessor250.invoke(Unknown Source) [:1.7.0_99] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) [rt.jar:1.7.0_99] at java.lang.reflect.Method.invoke(Method.java:606) [rt.jar:1.7.0_99] at org.ovirt.engine.core.utils.timer.JobWrapper.invokeMethod(JobWrapper.java:81) [scheduler.jar:] at org.ovirt.engine.core.utils.timer.JobWrapper.execute(JobWrapper.java:52) [scheduler.jar:] at org.quartz.core.JobRunShell.run(JobRunShell.java:213) [quartz.jar:] at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:557) [quartz.jar:]

hosted-engine stuck "failed liveliness check" "detail": "up"
by Paul Groeneweg | Pazion 17 Apr '16

17 Apr '16

Tonight my server with NFS hosted-engine mount crashed. Now all is back online ,except the hosted engine. I can't ping or ssh the machine when I do hosted-engine --vm-status, I get: .......... --== Host 2 status ==-- Status up-to-date : True Hostname : geisha-3.pazion.nl Host ID : 2 Engine status : {"reason": "failed liveliness check", "health": "bad", "vm": "up", "detail": "up"} Score : 3400 stopped : False Local maintenance : False crc32 : d71d7c6b Host timestamp : 4404 ............ I tried restarting all services/nfs mounts, start hosted engine on other hosts, but all the same host up, but liveliness failed and unable to access the network/IP. I imagine it is stuck at the console requiring a fsck check maybe? Is there a way to access the boot display directly? Any help is highly appreciated!

serial console and permission
by Nathanaël Blanchet 15 Apr '16

15 Apr '16

Hi all, I've successfully set up the serial console feature for all my vms. But the only way I found to make it work is to add each user as a UserVmManager role, whereas they have the SuperUser role at the datacenter level.I know there is an open bug on it for this. A second bug is that adding a group with UserVmManager as permission on a vm (instead of a simple user) doesn't allow to get the serial console. Thank you for your help
