Managing the AMASS File System
3-134 Command Reference 6-00028-01 Rev A
volcomp
Recover dead space by rewriting remaining data on a volume to
a different volume in the same volume group.
Dead space is space that has been previously written to by
AMASS. A volume that contains scattered files separated by
great expanses of dead space is a waste of media. This
command helps you to recycle this wasted space.
Note
This command is not valid for volumes in the space pool or in the
cleaning group.
Note
If you create a zero length file within an AMASS directory, ex.
"touch filename", the file is not associated with a volume or volume
group. This command will ignore such files. However, a zero length
file, i.e. a non-zero length file that was written to tape and then
truncated to zero length, will be recognized. Volcomp will not move
the file and will exit with “These are files left after volcomp.”
