Time Drift Issues
by Nur Imam Febrianto
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

Change Cluster CPU type
by Andrey Rusakov
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)

Update to 4.4.8 leaves cluster in a circular error-state
by Paul-Erik Törrönen
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.".

NFS storage was locked for 45 minutes after I attempted a clone operation
by David White
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?

posix storage mount path error when creating volumes
by Sketch
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):

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
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!
