Hello,
yes, I'm talking about gluster volumes.
"storages" not defined yet.
The main problem is about how to remove all definitions from gluster
configs on nodes and in ovirt too ( maybe oVirt will update
automaticaly , as U wrote before ).
1) nodes are in maintenance mode, glustred is running with errors

The log at /var/log/glusterfs/etc-glusterfs-glusterd.vol.log will give
you more information on the errors
2) all gluster data was cleared from filesystem ( meaning "
.glusterfs" , VM's data , etc. ( rm -rf ./.* ; rm -rf ./* = really
cleaned ) )

which of them are correct - both ??* - would I mix it ?? ( peers in
the same net, of course ( 16.0.0.0 ) )
If you want to add bricks using the 16.0.0.0 network, from ovirt you
will need to set this up like below
1. Define a network in the cluster with "gluster" network role.
2. After you add the hosts to ovirt using the 172.16.. network, assign
the "gluster" network to the 16.0.. interface using the "Setup Networks"
dialog.
Now when you create the volume from oVirt, the 16.0 network will be used
to add the bricks.
But in your case it looks like the same host is known as 2 peers - 1hp2
and 1hp2-SAN? Did you set this up from gluster CLI?
You could try peer detaching 1hp2-SAN and peer probing it again from
another host. (1hp2-SAN should be shown as other name for 1hp2)
Hostname: 1hp2-SAN
Uuid: 47b030ab-75d8-49ec-b67d-650e22dc2271
State: Peer in Cluster (Connected)
Hostname: 2hp2-SAN
Uuid: f98ff1e1-c866-4af8-a6fa-3e8141a207cd
State: Peer in Cluster (Connected)
Hostname: 2hp1-SAN
Uuid: 7dcd603f-052f-4188-94fa-9dbca6cd19b3
State: Peer in Cluster (Connected)
#*gluster volume delete 1HP-R2P1*
Deleting volume will erase all information about the volume. Do you
want to continue? (y/n) y

If you have removed only the gluster volumes and not the gluster
nodes - the oVirt engine will update the configuration with backend
gluster.
However, if the gluster nodes are also removed from backend - the
nodes should be in Non-responsive state in the UI?
You could put all nodes in gluster cluster in maintenance mode, and
forceremove(checkbox provided) the nodes.
