Marko,

From my understanding, you can have more than 3 hosts in a HCI cluster but to expand HCI you need to add hosts in multiples of three.  I.e. go from 3 hosts to 6 or 9 etc. 

You can still add hosts into the cluster as compute only hosts though.  So you could have 3 hosts with gluster and a 4th that is just compute.

Hi Strahil,

 

I circled back on your reply while ago regarding oVirt Hyperconverged and more than 3 nodes in cluster:

 

“Hi Marko, I guess  you can use distributed-replicated volumes  and oVirt  cluster with host triplets.”

Initially I understood that its limited to 3Nodes max per HC cluster, but now reading documentation further https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Maintenance_and_Upgrading_Resources.html that does not look like it.

 

Would you be so kind to give me an example or clarify what you meant by “you can use distributed-replicated volumes  and oVirt  cluster with host triplets.” ?

 

Kindly awaiting your reply.

Hi Strahil,

 

Thank you.

One maybe stupid question, but significant to me:

Considering i haven’t been playing before with hyperconverged setup in oVirt, is this something i can do from ui cockpit or does it require me first setup an Glusterfs on the Hosts before doing anything via oVirt API or Web interface?

 

Kindly awaiting your reply.

Dear oVirt,

 

Is it possible to add oVirt 3Hosts/Gluster hyperconverged cluster to existing oVirt setup? I need this to achieve Local storage performance, but still have pool of Hypevisors available.

Is it possible to have more than 3Hosts in Hyperconverged setup?

 

I have currently 1Shared Cluster (NFS based storage, where also SHE is hosted) and 2Local Storage clusters.

 

oVirt current version running is 4.3.4.

 

Kindly awaiting your reply.
