That's it, thanks.

From my ONTAP course notes:

wafl scan reallocate takes a volume or file and reallocates it on the disk to increase its layout efficiency (ie. defrags). However, you should only run this command on the advice of NetApp. It should only be run if volume capacity is <80% and during a non-peak period (filer impact similar to a vol copy command).

hope that helps

Don't know if this didn't get through or what so I'm reposting.

Thanks.

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.
