Unable to change compatibility version due to hosted engine
by Renout Gerrits
Hi All,
We have an environment which we want to upgrade to ovirt 4.0. This was
initially installed at 3.5, then upgraded to 3.6.
Problem we're facing is that for an upgrade to 4.0 a compatibility version
of 3.6 is required.
When changing the cluster compatibility version of the 'Default' cluster
from 3.5 to 3.6 we get the error in the gui: "Cannot change cluster
compatibility version when a VM is active. please shutdown all VMs in the
cluster."
Even when we shutdown all vm's, except for the Hosted Engine we get this
error.
On the hosts a 'vdsClient -s 0 list' is done which will return the HE.
In the engine logs we have the following error: "2016-12-08 13:00:18,139
WARN [org.ovirt.engine.core.bll.storage.UpdateStoragePoolCommand] (default
task-25) [77a50037] CanDoAction of action 'UpdateStoragePool' failed for
user admin@internal. Reasons:
VAR__TYPE__STORAGE__POOL,VAR__ACTION__UPDATE,$ClustersList
Default,ERROR_CANNOT_UPDATE_STORAGE_POOL_COMPATIBILITY_VERSION_BIGGER_THAN_CLUSTERS"
So problem would be that the HE is in the Default cluster. But how does one
change the compatibility version when the HE is down?
I've tried shutting down the engine, changing the version in the DB:
"UPDATE vds_groups SET compatibility_version='3.6';" and starting the
engine again.
When I do that and try to start a VM:
2016-12-09T13:30:21.346740Z qemu-kvm: warning: CPU(s) not present in any
NUMA nodes: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
2016-12-09T13:30:21.346883Z qemu-kvm: warning: All CPU(s) up to maxcpus
should be described in NUMA config
2016-12-09T13:30:21.355699Z qemu-kvm: "-memory 'slots|maxmem'" is not
supported by: rhel6.5.0
So that change was rolled back to compatibilty 3.5. After that we we're
able to start vm's again.
Please note that all hosts and HE are EL7.
To me this doesn't seem like a strange set-up or upgrade path. Would it be
possible to start the HE in another cluster than Default or is there a way
to bypass the vdsClient list check?
What is the recommended way of upgrading the HE in this case?
Kind regards,
Renout

dedicated gluster storage network
by Nathanaël Blanchet
Hi,
I changed the previous all in one network to a dedicated gluster storage
at the network level. But when doing netstat (or gluster peer status), I
can see that listening connection still use the previous vlan and
gluster bricks are probed on this vlan.
I detached them with ovirt or manually to probe them an other time, but
they are still probed on the initial ovirtmgmt vlan.
What is this gluster network supposed to do in reality?

could be. Check all the available options, but is simply an nfs mount
issue that is totally unrelated with ovirt

It means you can't reach that IP from your manager VM. Check your
network configuration of the manager. I had the same issue and i
solved by adding a secondary NIC to the manager VM in the same network
as the NFS storage (172.16.8.x in your setup).

I am pretty certain that this is not called fencing. Fencing is for hosts.
And it's meant for _stopping_ them, not starting.

No idea, but it might be possible using affinity rules and/or HA.
Changing the subject, to try to attract more relevant responses,
and adding Tomer.

ovirt, spice and igel
by Craig Warner
I’m new to overt and this has been a rapid learning curve, and come to point where I need assistance.
The objective of this project is to provide via a igel thin client a seamless multimedia experience for the end user.
The environment is based upon both host and virtual instance using Centos 7.2 and ovirt 4.0.
The igel thin client is designed to use the RHEV spice environment, so this is the first point of pain for this project. I can only the igel client to interact with the associating the firefox then finding the virt-viewer binary with the igel operating system. Not very seamless to provide multimedia experience for the end user.
igel terminal is running the latest update.
I’ve also engaged igel technical support but centos 7.2, and ovirt 4.0 seems to be breaking new ground.
Next point of pain is performance of multimedia on the thin client, less then satisfactory experience. Once again any helpful suggestions would be appreciated.
If I’ve left anything out in the description of what trying to achieve, let me know, and shall fill in the gaps.
Once again any assistance would be appreciated.
