Removing a Volume

Once a volume is no longer necessary (it is inactive and its contents have been archived,

for example), itis possibleto remove the volume and freeup thedisk space for other uses.

Before removing a volume, use the following procedure to stop all activity on the volume:

1. Remove all references to the volume by application programs, including shells, that

are running on the system.

2. If the volume is mounted as a ﬁle system, unmount it with this command:

# umount /dev/vx/dsk/diskgroup/volume

3. If the volume is listed in the /etc/fstab ﬁle, remove its entry by editing this ﬁle.

Refer to your operating system documentation for moreinformation aboutthe format

of this ﬁle and how you can modify it.

4. Stop all activity by VxVM on the volume with the command:

# vxvol stop volume

After following these steps, remove the volume with the vxassist command:

# vxassist remove volume volume

Alternatively, you can use the vxedit command to remove a volume:

# vxedit [-r] [-f] rm volume

The -r option to vxedit indicates recursive removal. This removes all plexes associated

with the volume and all subdisks associated with those plexes. The -f option to vxedit

forces removal. This is necessary if the volume is still enabled.
