 Specify the nodesize, the tree block size in which btrfs stores metadata. The
 default value is 16KiB (16384) or the page size, whichever is bigger. Must be a

 Smaller node size increases fragmentation but lead to higher b-trees which in
 turn leads to lower locking contention. Higher node sizes give better packing
