I updated to the latest Fedora 19 on two test servers, and now vdsmd will not start. Systedctl says this: dsmd.service - Virtual Desktop Server Manager Loaded: loaded (/usr/lib/systemd/system/vdsmd.service; enabled) Active: failed (Result: exit-code) since Mon 2013-10-14 12:31:30 EDT; 23h ago Process: 1788 ExecStart=/lib/systemd/systemd-vdsmd start (code=exited, status=139) Oct 14 12:31:30 rs0-ovirt0.rexdb.us python[1862]: DIGEST-MD5 ask_user_info() Oct 14 12:31:30 rs0-ovirt0.rexdb.us python[1862]: DIGEST-MD5 client step 2 Oct 14 12:31:30 rs0-ovirt0.rexdb.us python[1862]: DIGEST-MD5 ask_user_info() Oct 14 12:31:30 rs0-ovirt0.rexdb.us python[1862]: DIGEST-MD5 make_client_response() Oct 14 12:31:30 rs0-ovirt0.rexdb.us python[1862]: DIGEST-MD5 client step 3 Oct 14 12:31:30 rs0-ovirt0.rexdb.us systemd-vdsmd[1788]: /lib/systemd/systemd-vdsmd: line 185: 1862 Segmentation fault "$VDSM_TOOL" nwfilter Oct 14 12:31:30 rs0-ovirt0.rexdb.us systemd-vdsmd[1788]: vdsm: Failed to define network filters on libvirt[FAILED] Oct 14 12:31:30 rs0-ovirt0.rexdb.us systemd[1]: vdsmd.service: control process exited, code=exited status=139 Oct 14 12:31:30 rs0-ovirt0.rexdb.us systemd[1]: Failed to start Virtual Desktop Server Manager.

[Users] Using storage network for gluster
by Juan Pablo Lorier 06 Dec '13

06 Dec '13

H, I'm experimenting with gluster and as my DC is a iscsi dc, I've just created a new cluster with two hosts and now I'm trying to create a volume. I've followed all kind of guides in the web without success. Now I'm having ovirt to complaint about a network error in the volume creation and I'd like to ask two things: - Why I must use ovirtmgmt network for gluster (can't choose other from the add brick drop down list) instead of the network I have set up for iscsi? - What may be the problem with network? I get success on both hosts when I proob each other # gluster peer probe ovirt3.montecarlotv.com.uy peer probe: success: host ovirt3.montecarlotv.com.uy port 24007 already in peer list # gluster peer probe ovirt4.montecarlotv.com.uy peer probe: success: host ovirt4.montecarlotv.com.uy port 24007 already in peer list I get a lot of this ones in engine log: 2013-12-05 03:40:01,882 ERROR [org.ovirt.engine.core.bll.gluster.GlusterSyncJob] (DefaultQuartzScheduler_Worker-50) Error while refreshing Gluster lightweight data of cluster Penryn!: org.ovirt.engine.core.common.errors.VdcBLLException: VdcBLLException: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSNetworkException: org.apache.xmlrpc.XmlRpcException: <type 'exceptions.Exception'>:method "glusterVolumesList" is not supported (Failed with error VDS_NETWORK_ERROR and code 5022) at org.ovirt.engine.core.bll.VdsHandler.handleVdsResult(VdsHandler.java:122) [bll.jar:] at org.ovirt.engine.core.bll.VDSBrokerFrontendImpl.RunVdsCommand(VDSBrokerFrontendImpl.java:33) [bll.jar:] at org.ovirt.engine.core.bll.gluster.GlusterJob.runVdsCommand(GlusterJob.java:64) [bll.jar:] at org.ovirt.engine.core.bll.gluster.GlusterSyncJob.fetchVolumes(GlusterSyncJob.java:389) [bll.jar:] at org.ovirt.engine.core.bll.gluster.GlusterSyncJob.fetchVolumes(GlusterSyncJob.java:375) [bll.jar:] at org.ovirt.engine.core.bll.gluster.GlusterSyncJob.refreshVolumeData(GlusterSyncJob.java:346) [bll.jar:] at org.ovirt.engine.core.bll.gluster.GlusterSyncJob.refreshClusterData(GlusterSyncJob.java:104) [bll.jar:] at org.ovirt.engine.core.bll.gluster.GlusterSyncJob.refreshLightWeightData(GlusterSyncJob.java:83) [bll.jar:] at sun.reflect.GeneratedMethodAccessor99.invoke(Unknown Source) [:1.7.0_45] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) [rt.jar:1.7.0_45] at java.lang.reflect.Method.invoke(Method.java:606) [rt.jar:1.7.0_45] at org.ovirt.engine.core.utils.timer.JobWrapper.execute(JobWrapper.java:60) [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:] So I guess there's something with gluster version maybe: glusterfs.x86_64 3.4.0-8.el6 @glusterfs-epel glusterfs-api.x86_64 3.4.0-8.el6 @glusterfs-epel glusterfs-cli.x86_64 3.4.0-8.el6 @glusterfs-epel glusterfs-fuse.x86_64 3.4.0-8.el6 @glusterfs-epel glusterfs-libs.x86_64 3.4.0-8.el6 @glusterfs-epel glusterfs-rdma.x86_64 3.4.0-8.el6 @glusterfs-epel glusterfs-server.x86_64 3.4.0-8.el6 @glusterfs-epel vdsm-gluster.noarch 4.13.0-11.el6 @ovirt-stable this are the main links I used to configure: http://www.andrewklau.com/returning-to-glusterized-ovirt-3-3/ http://www.gluster.org/2013/09/ovirt-3-3-glusterized/ Regards

Re: [Users] VM with stateless snapshot won't start

Hello Dafna, > If a failure happened and the stateless vm has shut down without delete > of the snapshot, the next time you will try to run it we will try to > delete the snapshot. > from the engine log, it seems that there is a problem deleting the > snapshot because of quota. > can you please try to disable the quota and try to run the vm again? Quota were not enabled on this Data Center, I have never done anything with quota on oVirt. The 'quota' table was empty, and the 'quota_id' field on all VMs in the 'vm_static' table was NULL. Since it was seemingly trying to set the quota_id for this particular VM to '00000000-0000-0000-0000-000000000000', I manually inserted a record into the quota table using this ID. After that, I was able to start te VM. The quota_id field for the VM now contains a reference to this fake id. > Please note that the first time you will run it after disabling the > quota, the snapshot should be deleted but the vm will still not start. > only after the snapshot is deleted you will be able to run the vm again. Indeed, it took two attempts to start the VM. Question: is it harmful to leave the fake quota record with id '00000000-0000-0000-0000-000000000000' and the reference to it in the vm_static table in place?

After a restart of Engine, the message that I got was different, something about no host being available with enough memory (which was correct). So I guess an Engine restart fixed it, even though the initial migration task still shows as unfinished in the Tasks panel. Cheers, Martijn.

[Users] Failing migration, inconsistent state
by Martijn Grendelman 05 Dec '13

Hi, I tried to migrate several VMs from one host to another. Two VMs migrated without issues, but for one VM, the migration didn't happen. It seems to be hanging, but the UI is now in an inconsistent state: - The 'Tasks' tab reports 0 active tasks, but the last task (the migration in question) is still reported as 'Executing'. - The VM status is 'Up' (not migrating) - 'Migrate' action is choosable from menu, while 'Cancel Migration' is greyed out, but when I choose 'Migrate' and pick a host, I am told 'Cannot migrate VM. VM <name> is being migrated.'. What is the best way to fix this? Met vriendelijke groet, Martijn Grendelman
