It looks the gluster uuid saved in the ovirt engine db does not match the
one returned from CLI
Was this host reinstalled?
You may need to remove host from engine and add it again. If that doesn't
work you may need to manually change the uuid value in the database
(gluster_server table)
Removing host did nothing, indeed I had to go to the gluster_server table
to remove any disconnected host uuid, but it was not enough. Then I had
then to remove the host and reinstall it as a new host.
Thank you, I've been spending a lot of time to solve this issue.
Sorry to hear that you had trouble with this. Could you explain a bit on
how you got into this state?
Was it because you re-provisioned one of the gluster nodes and the gluster
UUID was reset (without oVirt being aware of it?). Would like to either
fix/enhance the engine to handle this if it's a common enough use-case
