Sometimes scratch2 becomes inacessible. This guide should help get it up and running again.

If /export/users/scratch2 is empty:

Applications > System Tools > Terminal

  $ sudo mount --bind /home/users/scratch2 /export/users/scratch2

Restart NFS

  $ sudo service nfs-kernel-server restart

Login to node as someone with sudo

If control has a different IP:

 $ sudo nano /etc/hosts

and change to the correct ip (check on brayton with ifconfig)

Unmount scratch2 and remount

$ sudo umount -l /home/users/scratch2
$ sudo mount /home/users/scratch2
