[linux-lvm] lvremove: 'snapshot': can't remove 'active'? , non-mounted file system







lvremove -v /dev/Home/2010.06.27-06.18.55
   Using logical volume(s) on command line
 Can't remove open logical volume "2010.06.27-06.18.55"

But it isn't mounted.

So why is it saying it is 'open':

ll /dev/mapper shows:


crw-rw---- 1  10, 58 2010-02-02 21:08 control

So 252 is the mapper device?

Is my real Home partition on 252,1?

I just got a backup error when I tried to backup Home,
which would correspond to 252,2 above.  It thinks it
is no longer the same file system as the previous backup,

Should I be backing up Home-Home-real?  That doesn't
seem right...
