# umount d8 # metaclear d8 d8: Concat/Stripe is cleared (Edit the /etc/vfstab file)
This example illustrated clearing the concatenation d8 that also contains a mounted file system. The file system must be unmounted before the volume can be cleared. The system displays a confirmation message that the concatenation is cleared. If there is an entry in the /etc/vfstab file 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.
