I posted that I had wiped out the oVirt-engine.. running cleanup on all three nodes. Done a re-deployment. Then to add nodes back.. though all have entries for eachother in /etc/hosts and ssh works fine via short and long name.
I added nodes back into cluster.. but had to do it via IP to get past error.
Now, if I go to create a volume via the GUI in gluster I get:
Error while executing action Create Gluster Volume: Volume create failed: rc=30800 out=() err=["Host 172_16_100_102 is not in 'Peer in Cluster' state"]
Which seems to be related to using IP vs DNS to add gluster volumes
Question: how do i fix the hosts in cluster being defined by IP vs desired hostname?
