Removing a RAID-0 Volume

How to Remove a RAID-0 Volume

Make sure that you have a current backup of all data and that you have root privilege.
Make sure that you no longer need the volume.
If you delete a stripe or concatenation and reuse the slices that were part of the deleted volume, all data on the volume is deleted from the system.
Unmount the file system, if needed.
```
# umount /filesystem
```
To remove a volume, use one of the following methods:
- From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node. Choose Edit⇒Delete, then follow the onscreen instructions. For more information, see the online help.
- Use the following format of the metaclear command to delete the volume:
```
metaclear volume-name
```
  See the following example and the metaclear(1M) man page for more information.

Example 9-8 Removing a Concatenation

# umount d8
# metaclear d8
d8: Concat/Stripe is cleared
(Edit the /etc/vfstab file)

This example illustrates removing the concatenation, d8, that also contains a mounted file system. The file system must be unmounted before the volume can be removed. The system displays a confirmation message that the concatenation is removed. If an entry in the /etc/vfstab file exists for this volume, delete that entry. You do not want to confuse the system by asking it to mount a file system on a nonexistent volume.
