Ignore the previous message, it turned out to be bogus. So now
resizing is implemented as follows:
- new-thin still takes a size arg
new-thin <id> <size in sectors>
- There is a resize message:
resize <id> <size in sectors>
- The target length doesn't have to correspond to the size of the thin
device. Writes beyond the end will cause IO error.
- Multiple targets may point to the same thin device. If you make
more than one active then it is a user error. Much like using a
linear target to map multiple devices to the same physical disk.
