free space on the data device drops below this level then a dm event
will be triggered which a userspace daemon should catch allowing it to
extend the pool device. Only one such event will be sent.
-Resuming a device with a new table itself triggers an event so the

-already exceeds the threshold.

+No special event is triggered if a just resumed device's free space is below
+the low water mark. However, resuming a device always triggers an
+event; a userspace daemon should verify that free space exceeds the low
+water mark when handling this event.

A low water mark for the metadata device is maintained in the kernel and
will trigger a dm event if free space on the metadata device drops below
