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

Hello everybody,
We are using oVirt Engine Version: 4.0.6.3-1.el7.centos on centos 7.3 with gluster replica 3 arbiter = (1+1)+1
I'm confused with GUI delaying - if node details are wanted ( cluster -> nodes -> node detail = click on node raw ) then request generate over 10 min delay to display details. This unexpected mistake didn't occure initially, but later - not specified when .
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?
The followed partial list of "engine.log" shows requests to "arbiter node" ( 16.0.0.159) connectivity. This requested 3rd node of gluster(arbiter) is NOT included in oVirt environment and will NOT. Maybe this is that problem, but I'm not shure, especially how to fix this.
Any reason why the Arbiter node will not be managed by oVirt?
