ovirt upgrade 4.1 -> 4.2: host bricks down
by Alex K 20 Jun '18

20 Jun '18

Hi all, I have a ovirt 2 node cluster for testing with self hosted engine on top gluster. The cluster was running on 4.1. After the upgrade to 4.2, which generally went smoothly, I am seeing that the bricks of one of the hosts (v1) are detected as down, while the gluster is ok when checked with command lines and all volumes mounted. Below is the error that the engine logs: 2018-06-17 00:21:26,309+03 ERROR [org.ovirt.engine.core.bll.gluster.GlusterSyncJob] (DefaultQuartzScheduler2) [98d7e79] Error while refreshing brick statuses for volume 'vms' of cluster 'test': null 2018-06-17 00:21:26,318+03 ERROR [org.ovirt.engine.core.vdsbroker.gluster.GetGlusterLocalLogicalVolumeListVDSCommand] (DefaultQuartzScheduler2) [98d7e79] Command 'GetGlusterLocalLogicalVolumeListVDSCommand(HostName = v0.test-group.com, VdsIdVDSCommandParametersBase:{hostId='d5a96118-ca49-411f-86cb-280c7f9c421f'})' execution failed: null 2018-06-17 00:21:26,323+03 ERROR [org.ovirt.engine.core.vdsbroker.gluster.GetGlusterLocalLogicalVolumeListVDSCommand] (DefaultQuartzScheduler2) [98d7e79] Command 'GetGlusterLocalLogicalVolumeListVDSCommand(HostName = v1.test-group.com, VdsIdVDSCommandParametersBase:{hostId='12dfea4a-8142-484e-b912-0cbd5f281aba'})' execution failed: null 2018-06-17 00:21:27,015+03 INFO [org.ovirt.engine.core.bll.lock.InMemoryLockManager] (DefaultQuartzScheduler9) [426e7c3d] Failed to acquire lock and wait lock 'EngineLock:{exclusiveLocks='[00000002-0002-0002-0002-00000000017a=GLUSTER]', sharedLocks=''}' 2018-06-17 00:21:27,926+03 ERROR [org.ovirt.engine.core.bll.gluster.GlusterSyncJob] (DefaultQuartzScheduler2) [98d7e79] Error while refreshing brick statuses for volume 'engine' of cluster 'test': null Apart from this everything else is operating normally and VMs are running on both hosts. Any idea to isolate this issue? Thanx, Alex

cloud-init reverting static network settings to DHCP on shutdown and restart
by geoff.carr＠beazley.com 19 Jun '18

19 Jun '18

Setting static network settings in the "Initial Run" section works fine when deploying a VM from template. When using "Run" to start the VM, customization works as expected. On a reboot the network settings are maintained however if the VM is shutdown and restarted the settings are reverted to DHCP. When editing the VM the cloud-init settings are still set and a visible in the "Initial Run" section. cloud-init (0.7.9-24.el7.centos) - Previously 0.7.9-20.el7.centos but upgraded to see if it would fix the issue. oVirt engine (4.2.4.1-1.el7) Guest OS (CentOS Linux release 7.4.1708) There is another thread that reports exactly the same issue and behavior here: - https://lists.ovirt.org/pipermail/users/2018-March/087860.html Grateful for any thoughts or assistance. Regards Geoff

Hardering oVirt Engine
by Punaatua PK 19 Jun '18

19 Jun '18

Hello, we are subject to PCI-DSS. I have some questions. We currently have setup oVirt in our environnement. We created 2 Datacenter. - one with a cluster with hosted engine on gluster (Hyperconverged env) which represents the "LAN" part - one with a cluster with gluster storage wich is the DMZ In PCI-DSS we have to secure communication (use HTTPs as much as possible). I did saw that ovirt-ha-agent (on hosted-engine capable host) check the status of the engine by sending GET request on the hosted-engine on port 80 (the same check that hosted-engine --vm-status did in fact). Since ovirt 4.2.2, with the introduction of gluster eventing, a new flow (HTTP post resquest) is needed from gluster nodes to the engine. (In my case, it's a flow from the DMZ to the LAN part in HTTP (non secure) Here is my question. Is it possible to "hardering" this part of the engine ? Another question out of PCI scope. Events like warning and error in the dashboard are clean each days. I tried to find which process did that (look into /etc/cron.daily, root crontab, etc) on the engine without succes. Is there any maintenance task that is run periodicaly ? Could we have the list of all the engine's task ? (regulary check the status of host, vm, storage) also the frequency ? I would appreciate the help. (Great great product ovirt !) Thank you for your jobs ! We did manage KVM hypervisor as standalone machine without all the power that libvirt provides. No need to spend lot of money into licencing product (VSphere and co)

Re: Ovirt + Gluster : How do I gain access to the file systems of the VMs
by Hanson Turner 19 Jun '18

Hi Guys, I've an answer... Here's how I did it... First, I needed kpartx ... so #apt-get install kpartx Then setup a loopback device for the raw hdd image #losetup /dev/loop4 [IMAGE FILE] #kpartx -a /dev/loop4 This allowed me to mount the various partitions included in the VM. There you can modify the configs, make backups etc. Thanks, Hanson On 06/19/2018 09:31 AM, Hanson Turner wrote: > > Hi Sahina, > > Thanks for your reply, I can copy the files off without issue.

General failure
by nicolas＠devels.es 19 Jun '18

19 Jun '18

Hi, We're running oVirt 4.1.9 (we cannot upgrade at this time) and we're having a major problem in our infrastructure. On friday, a snapshots were automatically created on more than 200 VMs and as this was just a test task, all of them were deleted at the same time, which seems to have corrupted several VMs. When trying to delete a snapshot on some of the VMs, a "General error" is thrown with a NullPointerException in the engine log (attached). But the worst part is that when some of these machines is powered off and then powered on, the VMs are corrupt... VM myvm is down with error. Exit message: Bad volume specification {u'index': 0, u'domainID': u'110ea376-d789-40a1-b9f6-6b40c31afe01', 'reqsize': '0', u'format': u'cow', u'bootOrder': u'1', u'address': {u'function': u'0x0', u'bus': u'0x00', u'domain': u'0x0000', u'type': u'pci', u'slot': u'0x06'}, u'volumeID': u'1fd0f9aa-6505-45d2-a17e-859bd5dd4290', 'apparentsize': '23622320128', u'imageID': u'65519220-68e1-462a-99b3-f0763c78eae2', u'discard': False, u'specParams': {}, u'readonly': u'false', u'iface': u'virtio', u'optional': u'false', u'deviceId': u'65519220-68e1-462a-99b3-f0763c78eae2', 'truesize': '23622320128', u'poolID': u'75bf8f48-970f-42bc-8596-f8ab6efb2b63', u'device': u'disk', u'shared': u'false', u'propagateErrors': u'off', u'type': u'disk'}. We're really frustrated by now and don't know how to procceed... We have a DB backup (with engine-backup) from thursday which would have a "sane" DB definition without all the snapshots, as they were all created on friday. Would it be safe to restore this backup? Any help is really appreciated... Thanks.

glusterfs-fuse consuming large amounts of ram
by Edward Clay 19 Jun '18

19 Jun '18

It looks like we are experiencing a bug in the version of glusterfs included with ovirt 4.2.3. It looks like glusterfs 3.12.x has an issue where it consumes large amounts of ram which has caused our HV report storage errors and pause VMs. https://bugzilla.redhat.com/show_bug.cgi?id=1496379 Is there a safe way to get glusterfs-fuse v3.13.x installed with ovirt 4.2.3 or do we have to live with this issue until future updates to ovirt/glusterfs are released? $ ssh hv1.domain.com "sudo grep glusterfs /var/log/messages-* | grep -i kill " /var/log/messages-20180610:Jun 6 13:49:54 hv1 kernel: Out of memory: Kill process 15353 (glusterfs) score 630 or sacrifice child /var/log/messages-20180610:Jun 6 13:49:54 hv1 kernel: Killed process 15353 (glusterfs) total-vm:33800604kB, anon-rss:31896632kB, file-rss:840kB, shmem-rss:0kB /var/log/messages-20180617:Jun 17 00:24:16 hv1 kernel: Out of memory: Kill process 4072 (glusterfs) score 678 or sacrifice child /var/log/messages-20180617:Jun 17 00:24:16 hv1 kernel: Killed process 4072 (glusterfs) total-vm:36159900kB, anon-rss:34338508kB, file-rss:888kB, shmem-rss:0kB We see this same issue occur on all hv in our cluster.

Ovirt + Gluster : How do I gain access to the file systems of the VMs
by Hanson Turner 19 Jun '18

19 Jun '18

Hi Guys, My engine has corrupted, and while waiting for help, I'd like to see if I can pull some data off the VM's to re purpose back onto dedicated hardware. Our setup is/was a gluster based storage system for VM's. The gluster data storage I'm assuming is okay, I think the hosted engine is hosed, and needs restored, but that's another thread. I can copy the raw disk file off of the gluster data domain. What's the best way to mount it short of importing it into another gluster domain? With vmware, we can grab the disk file and move it from server to server without issue. You can mount and explore contents with workstation. What do we have available to us for ovirt? Thanks,
