scratch usage order of precedence

 

Basically, pooled scratch space works by following this order of precedence:

  • the first scratch disk in the list will be used to volume capacity,
  • then the next scratch disk in the node confirmation file pool will be used to volume capacity and, so forth, through all defined scratch spaces in the pool,
  • When all scratch disks defined on each node are consumed, $TMPDIR  is used as the scratch disk to volume capacity, and
  • When $TMPDIR used to volume capacity, then the /tmp location is used.
