Logically speaking it seems the next to try would be -musage=40, 50 and so on.
But even so, the current physical space taken up by metadata is 88 GB, with
36 GB of actual metadata (72 GB in RAID1). So the potential gain here is only
16 GB at best.
It looks like the rest of the "free" 256 GB is really scattered across data
extents, even those beyond 90% utilization. To reclaim that into unallocated
it could take balancing with the 95-98 filter or no filter at all, and a
very long time.
