@ -112,9 +112,11 @@ $low_water_mark is expressed in blocks of size $data_block_size. If
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
userspace daemon can use this to detect a situation where a new table
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
