Hi all,

I'm not sure if you all have heard about Raft Consensus Algorithm, but from
the paper, video, and slides on the Internet, I think that this algorithm
can help to solve a lot of distributed cases in GlusterFS.

For example, right now the initial mounting of the filesystem can use any
nodes IP, and later when the application needs to read or write the data,
it will randomly picked from the peer list

With Raft, one of the node will act as a master, after successful election
among the peers. With one master in place, the read/write can directly goes
to the master, which will replicate to other follower, according to the
distribution requirement (distribute, replicate, stripe,
distribute-replicate, etc)

I also believe that with this method (having a master), the lock issue
happen with samba could be reduced or resolved.

For more information, please visit

and the paper
