Description Jonathan Earl Brassow 2016-11-08 13:56:27 UTC

Users should be able to change the regionsize of their RAID LV after creation - especially if it is in-sync.  Picking the wrong regionsize can result in poor performance.  People don't want to have to recreate their RAID because their choice (or the default value!) was bad.
