<<<<<<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?

Hi,
Can the replica position be configured ?
Could you give an example?
