Thanks for your patience Javier. I sure i get this running soon.
Problem now is when the system datastore is "shared" i have the same
problem. With "ssh" the image is copied to the node. Shall i set the
system datastore set back to "shared" and create symlinks one the nodes?
Question is. Do all datastore need to be one the mounted gluster volume?
best regards
Thomas
