3) Create a Domain within the Cluster
4) Add hosts to DC
5) Import Gluster Volume
4 & 5 not required if you change step 2 to import.
You are running into errors below because the engine sees the addition
of new hosts as gluster peer probing to a new cluster
Some issues. I create a DC, add a Cluster then add the Host to it.
Then
I try to add another the second node but it says It's already in a
cluster. There is no other cluster and the second host is not listed
anywhere.
So I try to remove the first host to restart from the beginning. It
says I can't remove the only host now till it's in maintenance.
Maintenance is grayed out. I wait a bit guessing there's background
processes running and can finally remove to readd.
When I try to redo the operation and get to the step of adding
another
host, I get:
"Error while executing action: Server mdskvm-p02.nix.mds.xyz
<http://mdskvm-p02.nix.mds.xyz> is already
part of another cluster."
But I can clearly see it's not there via another oVirt UI window.
oVirt:
ovirt-engine-4.2.1.7-1.el7.centos.noarch
Hosts:
root@mdskvm-p01: ovirt-host-4.2.3-1.el7.x86_64
root@mdskvm-p02: ovirt-host-4.2.3-1.el7.x86_64
System prevents me from removing and restarting the process again
with a:
