<p>Hello,</p>
<p>I upgraded my cluster of 8 hosts with gluster storage and
hosted-engine-ha. They were already Centos 7.3 and using Ovirt
4.0.6 and gluster 3.7.x packages from storage-sig testing.<br>
</p>
<p>I'm missing the storage listed under storage tab but this is
already filed by a bug. Increasing Cluster and Storage Compability
level and also "reset emulated machine" after having upgraded one
host after another without the need to shutdown vm's works well.
(VM's get sign that there will be changes after reboot).</p>
<p>Important: you also have to issue a yum update on the host for
upgrading additional components like i.e. gluster to 3.8.x. I was
frightened of this step but It worked well except a configuration
issue I was responsible for in gluster.vol (I had "transport
socket, rdma") <br>
</p>
<p>Bugs/Quirks so far:<br>
</p>
<p>1. After restarting a single VM that used RNG-Device I got an
error (it was german) but like "RNG Device not supported by
cluster". I hat to disable RNG Device save the settings. Again
settings and enable RNG Device. Then machine boots up. <br>
I think there is a migration step missing from /dev/random to
/dev/urandom for exisiting VM's.</p>
<p>2. I'm missing any gluster specific management features as my
gluster is not managable in any way from the GUI. I expected to
see my gluster now in dashboard and be able to add volumes etc.
What do I need to do to "import" my existing gluster (Only one
volume so far) to be managable ? <br>
</p>
<p>3. Three of my hosts have the hosted engine deployed for ha.
First all three where marked by a crown (running was gold and
others where silver). After upgrading the 3 Host deployed hosted
engine ha is not active anymore.</p>
<p>I can't get this host back with working ovirt-ha-agent/broker. I
already rebooted, manually restarted the services but It isn't
able to get cluster state according to <br>
"hosted-engine --vm-status". The other hosts state the host status
as "unknown stale-data"</p>
<p>I already shut down all agents on all hosts and issued a
"hosted-engine --reinitialize-lockspace" but that didn't help.<br>
</p>
<p>Agents stops working after a timeout-error according to log:</p>

</tt><br>
</p>
<p>The gluster volume of the engine is mounted corrctly in the host
and accessible. Files are also readable etc. No clue what to do.<br>
</p>
<p>4. Last but not least: Ovirt is still using fuse to access
VM-Disks on Gluster. I know - scheduled for 4.1.1 - but it was
already there in 3.5.x and was scheduled for every release since
then. I had this feature with opennebula already two years ago and
performance is sooo much better.... So please GET IT IN !<br>
</p>
<p>Bye<br>
