bump if anybody has an idea how to remove the NFS mounts from this server? I am going to the DC tomorrow to work on the NFS server, but I won't use it anyways with this PVE.
Simply start your nfs servers. If that is not possible, try to umount manually, which may also fail if the NFS server is still down. You can also remove the nfs serevr form /etc/pve/storage.cfg and reboot the node.
Just to post that this is now fixed. I deleted the 2 NFS mount points from the /etc/pve/storage.cfg file and did NOT reboot at that time. I drove to the DC about an hour away and by the time I got there the webadmin was fixed, I could log in and both NFS mounts were gone from the storage menu.
