This is a general ZFS pool question, not specific to FreeNAS.
One of my root pools is badly fragmented. It's a 20GB mirrored pool with 72% fragmentation right
now, (but only 52% used).
Would a ZFS send & receive from existing root pool to a newly created pool reduce fragmentation?
Basically I can break off a mirror and use it for the destination. (And yes, I have excellent backups.)
Back story. This is my minture media server running Linux with ZFS. Originally built without space
on the 2TB spinning rust for a mirror of "/boot" or "swap". Thus, my backup, repartition and restore
of the Media on it, which reduced the fragmentation to 1% or so, down from 11%. (And now I have
room to mirror "/boot" and "swap".)
