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 <a class="moz-txt-link-freetext" href="http://review.gluster.org/#/c/12250/">http://review.gluster.org/#/c/12250/</a> gives you
some information on the steps to run.<br>
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.<br>
