I believe you would have to either combine the drives with raid or lvm so
it’s presented as one device or just create multiple storage domains

Def. Quota Nir Soffer :


Hyperconverged uses gluster, and gluster uses replication (replica 3 or
replica 2 + arbiter) so adding raid below may not be needed.


Yes, I know this, but there is a way from the UI to create the storage  
domain using more then one disk?
I can't understand this in the guide available at  
https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Deploying_Hyperconverged.html




You may use the SSDs for lvm cache for the gluster setup.



That would be great!



I would try to ask on Gluster mailing list about this.


Thank you, I'm waiting for your news.

The hosted engine storage donain is small and sould run only one VM, so you
probably don't need 1.2T disks for it.

You may use the SSDs for lvm cache for the gluster setup.

Is this configuration supported or I have to change something?

Amd is giving higher memory bandwidth and higher bang/buck ratio with more 
cores per $ compared to intel - so I wouldn't recommend intel.

I guess you can try with installing an older version (v 4.2.X) and then upgrade 
the cluster to 4.3 .

Good Luck and Welcome to oVirt.

Hi Benedetto,

we have a running cluster with the same machine and a similar
configuration, currently we haven't encounter any issue. We're running
ovirt 4.3.7.

Hi,

Recently it was mentioned that there were some issues with the 'too
new' EPYC.

For now, you can do :
1. Use some old machines for initial setup of the HostedEngine VM
(disable all Spectre/Meltdown in advance) -> and then add the new
EPYC-based hosts and remove the older systems. Sadly, the older
systems cannot be too old :)

2. Host the HostedEngine VM on your current VmWare environment or on
a separate KVM host. Hosting the HostedEngine on bare metal is also OK

3. Wait (I don't know how long) till EPYC issues are solved.

Best Regards,Strahil Nikolov

Maybe it's better to use Intel processors?
