+ | Well, lvm really, really wants to make sure your stuff is there, even it the underlying volume is renamed, or even reformatted. Even after you remove the lv's, the vg's and the pv's, sometimes you still can not get it to do anything | ||
+ | |||
+ | <code bash> | ||
+ | # sometimes helpful to remove the dm's first, but not always necessary | ||
+ | dmsetup ls | ||
+ | dmsetup remove < | ||

+ | # releases everything | ||
+ | lvchange -an < | ||
+ | vgchange -an < | ||
