Rebuilding system disk?

» close window

The Question is:

The system disk has become full on a node of my vms cluster and set volume
 /rebuild doesn't seem to free any space after deleting some files.  (I have
 dismounted the disk from the cluster on all other nodes)
Is there a way of forcing a rebuild on reboot for a system disk as it doesn't
 seem to mount it anywhere using the mount command.
On alpha 4000 using 2.1gb disk on PCI scsi disk from internal scsi card

The Answer is :

  The system disk automatically rebuilds on system boot, unless the
  value of the system parameter ACP_REBLDSYSD has been altered.
  Rebuilding the disk is not normally a technique used for freeing
  up disk space, and there is no expectation that different nodes
  in a cluster will having differing views of freespace on a shared
  disk -- differing views of freespace would indicate a corruption.
  Note that the displayed value of the volume freespace is not
  considered when updating the volume (though the display value is
  updated), and updates to the freespace value can be lost and the
  value displayed can drift under certain circumstances -- dismounting
  and remounting the volume will reset the displayed value.
  An upgrade to OpenVMS Alpha V7.1-2 or V7.2-1 is recommended.
