thanks
ok
vgsplit/merge instead
and after that lvconvert-s
yes, I am aware of the issues with corruption
but if the cow device has all data, than no corruption will happen, right?
if COW has a copy of all blocks
than a lvconvert —merge, or mount of the snapshot volume will be without issues
If the 'COW' has all the data - why do you need then snapshot ?
Why not travel whole LV instead of snapshot ?
Also - nowdays this old (so called 'thick') snapshot is really slow compared
with thin-provisioning - might be good if you check what kind of features
you can gain/loose if you would have switched to thin-pool
(clearly whole thin-pool (both data & metadata) would need to travel between
your VGs.)
