Is it possible to _force_ deactivate a logical volume in lvm2? I've tried # lvchange -an /dev/vg/foo, but I get LV vg/foo in use: not removing I want to test some raid function(raid 5, inside xen domU) so I need to deactivate the logical volume. Searched google but cannot find something useful... Any idea? Thank you! -- ck.Choy choylists at gmail dot com
