Determining the Amount of Free Disk From the Command-Line

Lists the command to display the amount of free disk space.

To determine the amount of used and available disk space on the file system, run df -h. When running this command, if:

• The given path points to the mount point, the output will display used and available disk space for the entire cluster. For example:

  [root@atsqa6c69 ~]df -h /mapr/clus.posix/
  Filesystem            Size  Used  Avail  Use%  Mounted on 
  posix-client-basic    4.4T  9.7G  4.4T   1%    /mapr

• The given path points to a volume with no (hard) quota, the output will display used and available disk space for the entire cluster. For example:

  [root@atsqa6c69 ~]df -h /mapr/clus.posix/vol3
  Filesystem          Size  Used  Avail  Use%  Mounted on
  posix-client-basic  4.4T  9.7G  4.4T   1%    /mapr

• The given path points to a volume with (hard) quota set, the output will display the used and available disk space for the specific volume based on the allocated quota. For example:

  [root@atsqa6c69 ~]df -h /mapr/clus.posix/vol2/
  Filesystem          Size  Used  Avail  Use%  Mounted on
  posix-client-basic  5.0G  2.5G  2.6G   49%   /mapr
