It's my understanding that "--errorwhenfull y" will instantly fail
writes which imply new allocation requests, but writes to
already-allocated space will be completed.
It is possible, without messing directly with device mapper (via
dmsetup), to configure a strict "read-only" policy, where *all* writes
(both to allocated or not allocated space) will fail?
It is not possible to do via lvm tools, what/how device-mapper target
should be used?
