Hi everyone, I'm having a permissions problem after isolating a node from a cluster. I had 3 nodes on a cluster, then to switch to version 9 I shut down one node at a time, migrating the VMs to the remaining nodes, then reinstalled version 9 directly and created a new cluster. Now I have the last node left isolated from the old cluster, but I can't do anything, neither delete the VMs nor do the backup. In all cases, it gives me permissions denied. I tried to log in to the machine with the root user to change the permissions for the VM configuration, but it doesn't let me save the new permissions. It's as if the root user doesn't have the permissions, so how do I do the backups now? I'm attaching the error.
