Sorry, should of made that more clear. I'm using a DataProtect appliance to back up virtual machines. I need to add a NFS mount to the device so that a cron job can run certain tools from the mount nightly.
I've added the entry to /etc/fstab but upon mounting it (using mount -a) I get the error mentioned above. I am logging in with a user account I created on the appliance that has sudo perms, whether I run it as sudo mount -a or sudo to root and run it I receive the same error.
