How to use local storage on ARC's compute nodes

Background

On the ARC cluster mounts and provides access to a number of filesystems (storage devices or facilities), which are attached or mounted to it. Such filesystem is attached to a special auxiliary directory (folder) that is called a mount point. For example, all the home directories of all ARC's users are stored on in the /home directory, and the df command can show the details of filesystem that hold these data:

$ df -h /home
Filesystem        Size  Used Avail Use% Mounted on
netapp1:/ArcHome  250T  204T   47T  82% /home

So, we can see that the filesystem, ArcHome from the storage device netapp1 is mounted on the /home mount point.
