<<<<<<<<example: brick A ,brick B,brick C compose one volume
<<<<<<<<When client(fuse) in brick A write data into volume,for some
reason ,we want the data wrote into brick B or brick C.
<<<<<<<When a write is performed from a fuse mount, the response will not
come until the write happens on A, B, C. Order of the bricks does not
matter.

<<<<<<If the volume is configured to has only one replica or the volume
is a DHT one?
<<<<<Then the bricks are not in replication. Do you want to change the
position of the bricks?
Pranith
<<<<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.
Pranith
<<For safty thinking ,we want the data will be directed to any brick
except brick A.
<It depends on the hash the filename generates. It may very well end
up on brick-A. What is the usecase you want to address?
Pranith
We have some data in one disk of node (brick A),and want to put the
backup of the data into glusterfs.

Could you give an example?
