thanks for replying~~ but im still confused~~~
in client, what's the routine of an operation like "create"/"read" ,from client to server (even backend filesystem)?
"the GlusterFS metadata is stored as extended attributes to the files in the underlying filesystem"
well, after storing, how could i read the file and how to know where the file is located (or which server/brick the file is stored)
