Hi, I wonder if there are any thought about a relocate on write policy
for snapshot instead of copy on write policy used now?
instead of copy old one to snapshot, overwrite old one with new one, 2
writes and 1 reads. it is possible that write new data to a usused
i know later remove a snaphot will be a little trouble, but there must
be some way to get around it.
just a rough thought, any comment?
