Oops, this obviously happens with single or multiple device.

I also think the command needs to return some information about exactly where 
the end of the file system is, maybe in file system blocks? resize2fs states 
the number of fs blocks in the fs, after a resize. From that I can figure out 
the exact ending LBA needed when changing the partition table. Btrfs leaves me 
totally guessing what this value should be.
