Seems right to me.  Only up for a few minutes at 05:15 to give a cat water......

Normally root access is not "allowed" across NFS mounts.  You're logged in as root on the client.  I've not done this in a while so you'll have to check.....

On the server side you probably have root_squash specified in the exports file.  I think that needs to be changed to no_root_squash.  You have to unmount the file system on the client side, re-export the files system on the server side, and then remount on the client side.
