Finding Disk Storage Hogs?

» close window

The Question is:

We are receiving a warning that our disk drive is 92% full (on a 2.1 GB drive,
 it shows 4110480 total blocks and 293085 free blocks).  What is the best way
 to determine what file is causing this disk drive to be used so heavily?  Is
 there a way to list al
l files on the disk by order of size?  This is backup system to another
 identical system, so we know it should only use approximately 369 MB or 720801
Thanks, Ken

The Answer is :

  OpenVMS itself returns no such message -- accordingly, this would
  appear to be a layered product, third-party package, or local software.
  The DIRECTORY command offers various useful options -- though you
  do have a very old OpenVMS VAX version -- such as the following:
  This command displays only files with a minimum size of 1000 blocks.
  Also of interest will likely be an ANALYZE/DISK pass, as this can
  identify unused space remaining within the disk structure.
  Additionally, the disk quota mechanism -- when the quota for each user
  is set to a value larger than the disk itself -- can be used to track
  the disk use.
  Also see the DFU tool available on the Freeware.
