Without addressing the main question, a couple targets of opportunity: 1) A quick balance with -mprofiles=single should kill those unused single metadata and system mkfs.btrfs legacies so you don't have to see them in fi df. 2) While fi df reports the data total vs. used spread being close enough that it's unsurprising a balance -dusage=80 didn't give you anything back, the spread on metadata is rather higher, dup, 6.0 gig total, less than 1 gig used, so a balance -musage=50 or 80 should return a few gigs, 4-5 I'd guess, leaving you 1-2 gig metadata total. Maybe that's part of the missing snapshot overhead? (The -musage run should kill the unused single profile metadata/system as well, but for a different reason, so I made it a different point and used -mprofiles=single there to avoid conflating the two.) -- Duncan - List replies preferred.
