Hey Sahina,
Thanks very much.
I've taken a quick glance and it does mention I need a third host which I don't have.
However, since I wrote, I removed everything. Had to force remove hosts however the gluster setup and data in it stayed (Or so I'm thinking).
I'll read the article more thoroughly however is there a specific procedure for adding existing oVirt gluster volumes back into a cluster?
One additional question. Is the sequence below correct?
1) Create Data Center 2) Create Cluster within the DC
When you create the cluster - there's an Import cluster option, if I remember correctly. This should discover the peers and volumes and add it to the engine 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 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:
