I’ve been handed an ovirt setup from a previous admin that has resigned from the company. It was setup more as a test bed and not a final solution. Storage is being mounted over NFS from local drives contained on one of the hosts. I’ve been seeing alerts about one particular host’s nic going up and down frequently and now I’m seeing some sanlock errors around the same time (I’m assuming probably related to the interface being up and down). Wondering how concerning this is and what might be causing it.
