Dear Sahina,
*Q:*
"Any reason why the Arbiter node will not be managed by oVirt?
*A:*
1) The arbiter node ( which running this oVirt too ) is not powerfull in
CPU/mem/lan sources to run VMs . Just only to keep master data and ovirt
envir.
2) We wan't to migrate VMs to this node ( arbiter )
I think the oVirt scheduling policy can be set to NOT run VMs on the
arbiter node. This is something you can explore to solve your first 2
points.
The reason it'll be helpful to have arbiter also managed by oVirt is so
that the maintenance and fencing logic are aware of the state of all nodes
in the cluster. There's logic added specific to gluster to ensure that
quorum is not lost while moving a node to maintenance/when a node is fenced.
3) Oracle DB requests licences for all nodes in cluster ( lic. per
each
available CPU socket in cluster ). Nobody will not spent money for
unuseable CPU socket , especially dedicated cluster user :-( )
For this one, I have no solution
From that reasons arbiter not in cluster included.
regards
Pavel

I don't think the delay in GUI has anything to do with the logs below. Are
there any logs related to retrieving node details?
