6.1 HP IBRIX X9000 Network Storage System CLI Reference (TA768-96057, June 2012)

ibrix_snapreclamation
Reclaims file system space used by deleted snapshots.
Description
After deleting snapshots, you can use the ibrix_snapreclamation command to reclaim the
file system space previously used by the snapshots. The reclamation task runs on an entire file
system, not on a specific snap tree within that file system. If a file system includes two snap trees,
space is reclaimed for both snap trees.
Synopsis
Run snapshot reclamation on a file system:
ibrix_snapreclamation -r -f FSNAME [-s {maxspeed | maxspace}] [-v]
The -s option specifies the snapshot reclamation strategy. With maxspeed, the reclamation task
reclaims only the most easily recoverable snapped space. This strategy reduces the amount of
runtime required by the reclamation task, but leaves some space potentially unrecovered (that
space is still eligible for later reclamation). With maxspace, the reclamation task recovers all
snapped space eligible for recovery. It takes longer and uses more system resources than maxspeed.
The default is maxspace.
Display summary status information for snapshot reclamation tasks:
ibrix_snapreclamation -l [-f FSLIST]
Display detailed status information for a snapshot reclamation task:
ibrix_snapreclamation -i [-f FSLIST]
Stop the specified snapshot reclamation task:
ibrix_snapreclamation -k -t TASKID [-F]
