Automount

Automount is the system that automatically mounts and unmounts network disks when the user requests access.

Important disks

Starting with Fedora 20 (2014), the most important disks /home, /strw0 and /software, ar no longer hard-mounted, but configured through a special type of automount (through systemd, for those who like to know the details). Most of this is transparent to users. Just don't despair if you don't see /software mounted on your computer, it will be available as soon as you need something from it.

Data disks

All data disks of desktops and compute nodes are available under /net: if machine eendracht has a local disk called /data1, this can be accessed from other systems as /net/eendracht/data1. Note that /net/machinename will give a listing of disks on this machine, but /net will not contain a listing of all available computers.

Named disks

Named disks are available onder /disks . Disk names are usually related to the research groups, e.g. /cosmos* for the cosmology group.

There are some tools to make work with all of those disks somewhat easier:

  • disks: This gives an overview of all available disks, or all disks matching a pattern, e.g. disks chem to get a list of the /disks/chem* disks and the machines that serve them, or use e.g. disks schie to get a list of the disks on workstation schie.
  • df: The standard Unix command df has been modified to know about disk groups, so you can type e.g. df cosmos to get a report on disk space on all of the disks of the cosmology group.
