[MooseFS-Users] Chunkserver is also a client

[Michael T. <mic...@ho...>]

Hi.
I've been meaning to ask this for some time now.
My current setup now is MooseFS 2.x with 1 Master, 1 Metalogger, 3 Chunkservers, and all files have copies=3 so that all chunkservers will each have a complete set of chunks.  There are >5 clients connecting to this setup.
Now, suppose that in one of the chunkservers, I mount mfs' root directory and start copying files to an external USB hard drive.
My question is: will the chunkserver retrieve chunks from the other chunkservers for the files I'm copying?  Or does the mfs client code contain logic to determine that the chunks needed are available locally and, thus, all chunks are read locally which would in theory make the copying process go as fast as it could.
