Note - you cannot 'remove' mappings 'in-use' (aka open count of a
device
is higher then 0 - see 'dmsetup info -c' output for this).
However you can replace such mapping with 'error' target - so the
underlaying device is relaxed - although we do not support this
in lvm2 - you would need to use 'dmsetup' for this (and open lvm2 RFE
if there would be some serious justifaction).
Not related to oVirt, but I would find a means to set an error target
with LVM quite useful - think about immediately stopping IO to/from
device in case some serious error happended. Using lvm rather than
dmsetup would be easier and less error prone.
Thanks.
