Time Drift Issues
by Nur Imam Febrianto 07 Sep '21

07 Sep '21

Hi All, Recently I got an warning in our cluster about time drift : Host xxxxx has time-drift of 672 seconds while maximum configured value is 300 seconds. What should I do to address this issue ? Should I reconfigure / configure ntp client on all host ? Thanks before. Regards, Nur Imam Febrianto Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows

Change Cluster CPU type
by Andrey Rusakov 06 Sep '21

06 Sep '21

We are using oVirt for several years. And we start with Xeon v2 CPUs. At this moment of time we got all v3 aтв we will chnage them to v4 in a month. So i would like to change Cluster default CPU to Haswell, But got error with custom cpu on HostedEngine. HostedEngine config is locked. Is there a solution to chnage HostedEngine cpu type? P.S. some problem with Cluster compability version (4.5 4.6)

Correct way to install VDSM hooks
by Shantur Rathore 06 Sep '21

06 Sep '21

Hi all, I am trying to install vdsm hooks (scratchpad) specifically. I can see that there are rpms available in https://resources.ovirt.org/pub/ovirt-4.4/rpm/el8/noarch/ but when I try to install using yum it says it cannot find it. Do I have to manually select the hook rpm and install it or am I missing something? Kind regards, Shantur

Update to 4.4.8 leaves cluster in a circular error-state
by Paul-Erik Törrönen 06 Sep '21

06 Sep '21

Having updated rpm-packages for a DC with a cluster containing 2 hosts (and executed the engine-setup on the engine machine), I now face the following issue: One of the VMs had a couple of snapshots and apparently this interferes with the upgrade of the cluster version, which currently is 4.4. The 4.4 has become incompatible with the chosen CPU architecture (Intel Westmere Family, the hosts are both Dell x10-series with Xeon X56xx CPUs) and requires an upgrade to newer compatibility version, 4.6 presumably, so the DC/Cluster state is "unknown". However I can't do this because the snapshots exists. I get the "Cannot change cluster version since following VMs are previewing snapshots:" listing a VM with snapshots. The snapshots in turn can not be Commit/Undo because: "Cannot revert to Snapshot. Unknown Data Center status.". So how do I break this circular error? The VM itself is not essential, it can be removed if that solves the case. However this can not be completed from the UI because: "Cannot remove VM. Unknown Data Center status.". Poltsi

NFS storage was locked for 45 minutes after I attempted a clone operation
by David White 03 Sep '21

03 Sep '21

I have an HCI cluster running on Gluster storage. I exposed an NFS share into oVirt as a storage domain so that I could clone all of my VMs (I'm preparing to move physically to a new datacenter). I got 3-4 VMs cloned perfectly fine yesterday. But then this evening, I tried to clone a big VM, and it caused the disk to lock up. The VM went totally unresponsive, and I didn't see a way to cancel the clone. Nagios NRPE (on the client VM) was reporting server load over 65+, but I was never able to establish an SSH connection. Eventually, I tried restarting the ovirt-engine, per https://access.redhat.com/solutions/396753. When that didn't work, I powered down the VM completely. But the disks were still locked. So I then tried to put the storage domain into maintenance mode, but that wound up putting the entire domain into a "locked" state. Finally, eventually, the disks unlocked, and I was able to power the VM back online. From start to finish, my VM was down for about 45 minutes, including the time when NRPE was still sending data to Nagios. What logs should I look at, and how can I troubleshoot what went wrong here, and hopefully avoid this from happening again? Sent with ProtonMail Secure Email.

posix storage mount path error when creating volumes
by Sketch 03 Sep '21

03 Sep '21

My cluster was originally built on 4.3, and things were working as long as my SPM was on 4.3. I just killed off the last 4.3 host and rebuilt it as 4.4, and upgraded my cluster and DC to compatibility level 4.6. We had cephfs mounted as a posix FS which worked fine, but oddly in 4.3 we would end up with two mounts for the same volume. The configuration had a comma separated list of IPs as that is how ceph was configured for redundancy, and this is the mount that shows up on both 4.3 and 4.4 hosts (/rhev/data-center/mnt/10.1.88.75,10.1.88.76,10.1.88.77:_vmstore/). But the 4.3 hosts would also have a duplicate mount which had the FQDN of one of the servers instead of the comma separated list. In 4.4, there's only a single mount and existing VMs will start just fine, but you can't create new disks or migrate existing disks onto the posix storage volume. My suspicion is this is an issue with the mount parser not liking the comma in the name of the mount from the error that I get on the SPM host when it tries to create a volume (migration would also fail on the volume creation task): 2021-08-31 19:34:07,767-0700 INFO (jsonrpc/6) [vdsm.api] START createVolume(sdUUID='e8ec5645-fc1b-4d64-a145-44aa8ac5ef48', spUUID='2948c860-9bdf-11e8-a6b3-00163e0419f0', imgUUID='7d704b4d-1ebe-462f-b11e-b91039f43637', size='1073741824', volFormat=5, preallocate=1, diskType='DATA', volUUID='be6cb033-4e42-4bf5-a4a3-6ab5bf03edee', desc='{"DiskAlias":"test","DiskDescription":""}', srcImgUUID='00000000-0000-0000-0000-000000000000', srcVolUUID='00000000-0000-0000-0000-000000000000', initialSize=None, addBitmaps=False) from=::ffff:10.1.2.37,43490, flow_id=bb137995-1ffa-429f-b6eb-5b9ca9f8dfd7, task_id=2ddfd1bc-d7e1-4a1e-877a-68e1c2a897ed (api:48) 2021-08-31 19:34:07,767-0700 INFO (jsonrpc/6) [IOProcessClient] (Global) Starting client (__init__:340) 2021-08-31 19:34:07,782-0700 INFO (ioprocess/3193398) [IOProcess] (Global) Starting ioprocess (__init__:465) 2021-08-31 19:34:07,803-0700 INFO (jsonrpc/6) [vdsm.api] FINISH createVolume return=None from=::ffff:10.1.2.37,43490, flow_id=bb137995-1ffa-429f-b6eb-5b9ca9f8dfd7, task_id=2ddfd1bc-d7e1-4a1e-877a-68e1c2a897ed (api:54) 2021-08-31 19:34:07,844-0700 INFO (tasks/5) [storage.ThreadPool.WorkerThread] START task 2ddfd1bc-d7e1-4a1e-877a-68e1c2a897ed (cmd=<bound method Task.commit of <vdsm.storage.task.Task object at 0x7f4894279860>>, args=None) (threadPool:146) 2021-08-31 19:34:07,869-0700 INFO (tasks/5) [storage.StorageDomain] Create placeholder /rhev/data-center/mnt/10.1.88.75,10.1.88.76,10.1.88.77:_vmstore/e8ec5645-fc1b-4d64-a145-44aa8ac5ef48/images/7d704b4d-1ebe-462f-b11e-b91039f43637 for image's volumes (sd:1718) 2021-08-31 19:34:07,869-0700 ERROR (tasks/5) [storage.TaskManager.Task] (Task='2ddfd1bc-d7e1-4a1e-877a-68e1c2a897ed') Unexpected error (task:877) Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/vdsm/storage/task.py", line 884, in _run return fn(*args, **kargs) File "/usr/lib/python3.6/site-packages/vdsm/storage/task.py", line 350, in run return self.cmd(*self.argslist, **self.argsdict) File "/usr/lib/python3.6/site-packages/vdsm/storage/securable.py", line 79, in wrapper return method(self, *args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/storage/sp.py", line 1945, in createVolume initial_size=initialSize, add_bitmaps=addBitmaps) File "/usr/lib/python3.6/site-packages/vdsm/storage/sd.py", line 1216, in createVolume initial_size=initial_size, add_bitmaps=add_bitmaps) File "/usr/lib/python3.6/site-packages/vdsm/storage/volume.py", line 1174, in create imgPath = dom.create_image(imgUUID) File "/usr/lib/python3.6/site-packages/vdsm/storage/sd.py", line 1721, in create_image "create_image_rollback", [image_dir]) File "/usr/lib/python3.6/site-packages/vdsm/storage/task.py", line 385, in __init__ self.params = ParamList(argslist) File "/usr/lib/python3.6/site-packages/vdsm/storage/task.py", line 298, in __init__ raise ValueError("ParamsList: sep %s in %s" % (sep, i)) ValueError: ParamsList: sep , in /rhev/data-center/mnt/10.1.88.75,10.1.88.76,10.1.88.77:_vmstore/e8ec5645-fc1b-4d64-a145-44aa8ac5ef48/images/7d704b4d-1ebe-462f-b11e-b91039f43637 2021-08-31 19:34:07,964-0700 INFO (tasks/5) [storage.ThreadPool.WorkerThread] FINISH task 2ddfd1bc-d7e1-4a1e-877a-68e1c2a897ed (threadPool:148) This is a pretty major issue since we can no longer create new VMs. As a workaround, I could change the mount path of the volume to only reference a single IP, but oVirt won't let me edit the mount. I wonder if I could manually edit in the database, then reboot the hosts one by one to make the change take effect without having to shut down hundreds of VMs at once?

Template for Ubuntu 18.04 Server Issues
by jeremy_tourville＠hotmail.com 02 Sep '21

02 Sep '21

I have built a system as a template on oVirt. Specifically, Ubuntu 18.04 server. I am noticing an issue when creating new vms from that template. I used the check box for "seal template" when creating the template. When I create a new Ubuntu VM I am getting duplicate IP addresses for all the machines created from the template. It seems like the checkbox doesn't fully function as intended. I would need to do further manual steps to clear up this issue. Has anyone else noticed this behavior? Is this expected or have I missed something? Thanks for your input!
