Removing a snapshot volume

If a snapshot volume is no longer needed, you can remove it and free up the disk space for other uses by using the vxedit rm command.

Prerequisites

  • You must be logged in as superuser.

  • If the volume is on a mounted file system, you must unmount it before removing the volume.

To remove a snapplan and snapshot volume

  1. To remove the snapshot and free up the storage used by it:

    • If the snapshot has been taken, remove the snapshot as follows:

        # vxsnap -g diskgroup dis snapshot_volume
 
  # vxvol -g diskgroup stop snapshot_volume
 
  # vxedit -g diskgroup -rf rm snapshot_volume

    • If the snapshot has not been taken and the snapshot plex (mirror) exists, remove the snapshot as follows:

        # vxsnap -g diskgroup rmmir volume

  2. Remove the DCO and DCO volume:

    # vxsnap -g diskgroup unprepare volume

  3. Remove the snapplan.

    # /opt/VRTS/bin/dbed_vmchecksnap -S PROD -f snapplan -o remove

    For example, the following commands will remove a snapshot volume from disk group PRODdg:

    # vxsnap -g PRODdg dis snap_v1
# vxvol -g PRODdg stop snap_v1
# vxedit -g PRODdg -rf rm snap_v1
