Determining the Amount of Free Disk

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

  • The given path points to the mountpoint, 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
