But the total thin storage pool is shared by multiple luns
and thus maybe multiple not-able-to-cooperate hosts.

I was only pointing this out because earlier threads seemed
to be "linux filesystems to be exact across multiple hosts"
(which is really a cluster design) and even if we did that
for linux it would not solve the customer need.

I just wanted to make it clear why trying to do a complicated
change to linux for exactness is pointless because the customer
requirement is for more than linux attached to the thin pool.

So the relevance is our design boundary.
