Removing a Volume

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

been archived, for example), it is possible to remove the volume and free

up the disk space for other uses.

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

activity on the volume:

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

shells, that are running on the system.

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

command:

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

Step 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 more

information about the format of this ﬁle and how you can modify it.

Step 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.
