I’m coming late to the party on this so forgive me, but I found that even using
QoS I could not even snapshot my filesets in a timely fashion, so my
rebalancing could only run at weekends with snapshotting disabled.

Subject: [gpfsug-discuss] Rebalancing with mmrestripefs -P
I have one storage pool that was recently doubled, and another pool migrated
there using mmapplypolicy.
The new half is only 50% full, and the old half is 94% full.
Disks in storage pool: cit_10tb (Maximum disk size allowed is 516 TB)

Will the command "mmrestripfs /gpfs -b -P cit_10tb” move the data blocks from
the _cit_ NSDs to the _george_ NSDs,
so that they end up all around 75% full?
Thanks,
