For
simplification,let`s suppose it being a DHT volume with three
bricks,there
is no replica.When
client(fuse) in
brick A write data into volume,for some reason ,we want the data
wrote
into brick B or brick C.
If it is DHT volume, then the data of the files will be residing
either in brick A, B, or C based on the hash of the filename and
layout of the directory not on all of the bricks A, B, C. Only the
directories are created on all the bricks A, B, C.
