[ovirt-users] Re: oVirt - Scaling out from one to many

Hello everyone,
I have two things that i really need to understand regarding storage
scaling using gluster.
Basically, I am trying to figure out a way to go from 1 single instance
to multiple nodes cluster.
1. Single node SelfHosted Engine HyperConverged setup - scale instance up
to 3 nodes:
- the gluster volumes are created as distributed type.
- is there a procedure to migate this single-host scenario to multiple
nodes, considering that the 3 nodes setup is using replica 3 gluster
volumes ?
Sahina, a quick check on the oVirt website didn't help me finding the
documentation for Leo.
Can you please assist?
2. 3 Nodes SelfHosted Engine - add more storage nodes
- how should I increase the size of the already present replica 3 volumes ?
- should the volumes be as distribute-replicated in an environment larger
than 3 nodes ?
Couldn't find documentation on ovirt.org site, but this should apply to
your case:
https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infr...
Sahina, can you help preparing some documentation for ovirt.org as well?
3. Is there a limit as a maximum number of compute nodes per cluster ?
I'm not aware of limits but according to above document I won't go over the
9 nodes in this configuration.
Thank you very much !
Leo
