[mkfs.xfs] By default, I get 29 for AGcount and the corresponding AGsize of ~1TB. Supposedly neither are adjustable, but that can't be true during xfs_grow.
My (uninformed) guess is that if I quadruple the size of my xfs filesystem (from 30TB to 120TB), then the number of aggregation groups will also quadruple.
It's adjustable upwards, but not quite downwards. (`xfs_growfs -D ...` apparently only works to the point where the highest-numbered AG has been shrunk to 64 blocks.)
