        All, 
        We have a small cluster with a single
          volume and a single replicated brick:
         
        Volume Name: volume1
        Type: Replicate
        Number of Bricks: 1 x 2 = 2
        Bricks:
        Brick1: node01:/export/sdb1/brick
        Brick2: node02:/export/sdb1/brick
         
        Now the disk on node01 is going bad and
          needs replaced, but I am uncertain if there is a safe way to
          do this with gluster. There are not enough connections in the
          system to hook up a new disk and then add it. I have to
          physically replace the disk with the new one.
      
    
    If you are using glusterfs 3.9 and want to give the replaced brick
    the same name as the old one, there is the reset-brick command. The
    commit message in http://review.gluster.org/#/c/12250/ gives you
    some information on the steps to run.

    If you are okay with using a different name for the brick, then
    there is `gluster volume replace-brick <volname>
    <hostname:old brick> <hostname:new brick> commit force`.
    I think this command works from glusterfs 3.7.10 onward.

        Is there a way to do that?
