mounted on
/mnt/lvol1
:
# umount /mnt/lvol1
2.

In the following example, the logical volume subject to the move belongs to the
vg01 volume group:
# vgchange -an vg01
0 logical volume(s) in volume group "vg01" now active
(4) Setting Up Xen
If Xen is being used, make sure that domainU has been stopped. If domainU has been

so that domainU will not start automatically.
