What exactly does 'wafl scan reallocate' do? Does it actually re-write data in a more efficient manner/layout? Or does it redo inodes and pointers in a more efficient layout without moving data?
I know that a reallocate is unnecessary if the measure_layout is low (most of mine are under 2) but on occassion I get higher numbers and wonder what it does to fix this.
Thanks.

Don't know if this didn't get through or what so I'm reposting.
Thanks.
It got through all right, but as "wafl scan" is an advanced mode command with no public documentation, perhaps you shouldn't have been too surprised that no-one has been able to reply to it yet ... Most of us probably didn't even know that it existed!
