Add a knob POOL_META_SIZE #253

Closed rhvgoyal closed 7 years ago

rhvgoyal commented 7 years ago

Right now thin pool metadata size is automatically determined. That is .1% of free space in volume group.

A user has asked for a knob to make it configurable. They want to allocate a larger metadata volume to start with. Looks like they run out of free space in metadata volume and VG is full and there is not enough space to grow it later.

Given their worklaod, they can allocate a bigger metadata volume using this knob at the beginning.
