If you have a snapshot of a volume running... how are you supposed to delete
it?

i.e. after you unmount it... if I just do a lvremove, I get a warning about it
being
an active volume -- so I tried doing a dmsetup remove on it first -- and that
stops the warning -- but I just noticed, I had a bunch of inactive 'cow'
volume names under 'dmsetup ls', that referred to the old snapshot names.
lvchange -an  vg/snapshot_lv

Ooops sorry - ignore this one - as this will work with some not yet release target

I'm confused.

First I tried:

# lvremove /dev/Home+Space/Home-2011.08.31-02.23.11
Do you really want to remove active logical volume Home-2011.08.31-02.23.11? [y/n]: ^C
 Logical volume Home-2011.08.31-02.23.11 not removed


Then, I tried what you had above:

# lvchange -an /dev/Home+Space/Home-2011.08.31-02.23.11 # lvremove /dev/Home+Space/Home-2011.08.31-02.23.11 Logical volume "Home-2011.08.31-02.23.11" successfully removed

Was it not supposed to work?



Does it work for you ?

If so - please post  -vvvv  trace.


So just post only  lvremove -vvvv  trace please.

It could be udev-related issue.
