Hi all, I see the following gluster hooks at ovirt cluster enabled: [image: image.png] What is their purpose? Do they need to be all enabled? Thanx, Alex

Re: ovirt 4.2.7.1 fails to deploy hosted engine on GlusterFS
by Johannes Jurgens Loots 09 Dec '18

09 Dec '18

I had this issue this week as well. When asked about the glusterfs that you self provisioned you stated "ovirt1.localdomain:/gluster_bricks/engine” So I am new to gluster but as a client of gluster you can only refer to it via volume name. host:/<volume name> Hence maybe try ovirt1.localdomain:/engine. That did the trick for me. Hope this helps. Cost me a week. Jurie

Strange migration issue
by Demeter Tibor 09 Dec '18

09 Dec '18

Dear All, I've using ovirt from 3.4 and we have a strange, rarely problem with live migrations. - In most of case impossible to do a live migrate of VMs that have a lot of memory (16 gigs and more up to 40 GB) . - Those are need to try and try until the migration will be successful - impossible to understand why does working in a case and doesn't in another - it is happening always if there bigger load on vms, but only on big memory VM-s - The small VMs (2-4-8 gigs) can migrate without problems - In very rarely cases possible to migrate on first try. - We using the memory ballooning function on all of VMs. We using dedicated migration network with separated vlans, but on same physical lan (1gbe) with ovirtmgmt. At this moment, we don't use QoS for dedicate bandwidth. What can I do ? Thanks in advance, Regards, Tibor

Removing stale unused disks from Ovirt Storage domains?
by Jacob Green 07 Dec '18

07 Dec '18

Hello, after migrating our Fiber Channel to a new Ovirt 4.2 environment, we over the years and through experimenting and mistakes have ended up with some stale LVM's/disks on our fibre channel storage that Ovirt no longer is able to manage correctly or is unaware of. I am looking for a reliable to way to do a few different things. The first is figuring out precisely what LVM ids belong to a VM and is being used by that VM. The second is figuring out if a LVM I have found on the Storage domain is being used at all by any VM or if ovirt is even aware of it. I have fumbled around a bit. And using a combination of the following I have been able to figure out some of them. But now I am finding information that does not match or may not be correct or I am interpreting the data wrong. Anyway this is a big deal, because we want to remove the stale unused LVMs and it would obviously be disastrous if I deleted the wrong LVM from the FC. So I know its not recommend but since I am not actually telling vdsm-client to do anything other than get information I figure its harmless. So here is what I have found so far. *vdsm-client Host getVMFullList vmname=<VM_NAME_HERE> | grep volumeID* *lvs | grep <noted volumeID here>* With the above I have had some success verifying what LVMs a device is using. However now I am having trouble figuring out a particular windows server VMs LVM id's. what I want to know is there a better way? Also two more things. You could call these feature requests, however it would be nice if there was a way to see all the unused LVMs on a storage domain that are not Tied to a VM. And it would also be nice to be able to remove un-imported VMs that reside on a storage domain without importing them. Anyway trying to get rid of un-imported vms and getting rid of unused LVMs has been a chore. I wish there was an easier way. -- Jacob Green Systems Admin American Alloy Steel 713-300-5690

VM ramdomly unresponsive
by fsoyer 07 Dec '18

07 Dec '18

Hi all, I continue to try to understand my problem between (I suppose) oVirt anf Gluster. After my recents posts titled 'VMs unexpectidly restarted' that did not provide solution nor search idea, I submit to you another (related ?) problem. Parallely with the problem of VMs down (that did not reproduce since Oct 16), I have ramdomly some events in the GUI saying "VM xxxxx is not responding." For example, VM "patjoub1" on 2018-11-11 14:34. Never the same hour, not all the days, often this VM patjoub1 but not always : I had it on two others. All VMs disks are on a volume DATA02 (with leases on the same volume). Searching in engine.log, I found : 2018-11-11 14:34:32,953+01 INFO [org.ovirt.engine.core.vdsbroker.monitoring.VmAnalyzer] (EE-ManagedThreadFactory-engineScheduled-Thread-28) [] VM '6116fb07-096b-4c7e-97fe-01ecc9a6bd9b'(patjoub1) moved from 'Up' --> 'NotResponding' 2018-11-11 14:34:33,116+01 WARN [org.ovirt.engine.core.vdsbroker.vdsbroker.VdsBrokerObjectsBuilder] (EE-ManagedThreadFactory-engineScheduled-Thread-1) [] Invalid or unknown guest architecture type '' received from guest agent 2018-11-11 14:34:33,176+01 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-28) [] EVENT_ID: VM_NOT_RESPONDING(126), VM patjoub1 is not responding. ... ... 2018-11-11 14:34:48,278+01 INFO [org.ovirt.engine.core.vdsbroker.monitoring.VmAnalyzer] (EE-ManagedThreadFactory-engineScheduled-Thread-48) [] VM '6116fb07-096b-4c7e-97fe-01ecc9a6bd9b'(patjoub1) moved from 'NotResponding' --> 'Up'So it becomes up 15s after, and the VM (and the monitoring) see no downtime. At this time, I see in vdsm.log of the nodes : 2018-11-11 14:33:49,450+0100 ERROR (check/loop) [storage.Monitor] Error checking path /rhev/data-center/mnt/glusterSD/victor.local.systea.fr:_DATA02/ffc53fd8-c5d1-4070-ae51-2e91835cd937/dom_md/metadata (monitor:498) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/storage/monitor.py", line 496, in _pathChecked delay = result.delay() File "/usr/lib/python2.7/site-packages/vdsm/storage/check.py", line 391, in delay raise exception.MiscFileReadException(self.path, self.rc, self.err) MiscFileReadException: Internal file read failure: (u'/rhev/data-center/mnt/glusterSD/victor.local.systea.fr:_DATA02/ffc53fd8-c5d1-4070-ae51-2e91835cd937/dom_md/metadata', 1, 'Read timeout') 2018-11-11 14:33:49,450+0100 INFO (check/loop) [storage.Monitor] Domain ffc53fd8-c5d1-4070-ae51-2e91835cd937 became INVALID (monitor:469) 2018-11-11 14:33:59,451+0100 WARN (check/loop) [storage.check] Checker u'/rhev/data-center/mnt/glusterSD/victor.local.systea.fr:_DATA02/ffc53fd8-c5d1-4070-ae51-2e91835cd937/dom_md/metadata' is blocked for 20.00 seconds (check:282) 2018-11-11 14:34:09,480+0100 INFO (event/37) [storage.StoragePool] Linking /rhev/data-center/mnt/glusterSD/victor.local.systea.fr:_DATA02/ffc53fd8-c5d1-4070-ae51-2e91835cd937 to /rhev/data-center/6efda7f8-b62f-11e8-9d16-00163e263d21/ffc53fd8-c5d1-4070-ae51-2e91835cd937 (sp:1230)OK : so, DATA02 marked as blocked for 20s ? I definitly have a problem with gluster ? I'll inevitably find the reason in the gluster logs ? Uh : not at all. Please see gluster logs here : https://seafile.systea.fr/d/65df86cca9d34061a1e4/ Unfortunatly I discovered this morning that I have not the sanlock.log for this date. I don't understand why, the log rotate seems OK with "rotate 3", but I have no backups files :(. But, luck in bad luck, the same event occurs this morning ! Same VM patjoub1, 2018-11-13 08:01:37. So I have added the sanlock.log for today, maybe it can help. IMPORTANT NOTE : don't forget that Gluster log with on hour shift. For this event at 14:34, search at 13h34 in gluster logs. I recall my configuration : Gluster 3.12.13 oVirt 4.2.3 3 nodes where the third is arbiter (volumes in replica 2) The nodes are never overloaded (CPU average 5%, no peak detected at the time of the event, mem 128G used at 15% (only 10 VMs on this cluster)).

Hi all, I am testing vGPU in ovirt4.2. I have a nvidia p100 GPU installed in the host and I have installed the correct dirver. I followed this page(https://www.ovirt.org/documentation/install-guide/appe-Preparing_a_Hos… but I failed. In the "Host Devices tab" I got an device called "GP100GL [Tesla P100 PCIe 16GB]". I could not find any device of "mdev type". Anyone can help me? Thanks a lot!
