<div>Dear list,</div>

</div>
<div>In a recent discussion on this list Ravi suggested that the
documentation for replace-brick¹ was out of date. For a
distribute–replicate volume the documentation currently says
that we need to kill the old brick's PID, create a temporary
empty directory on the FUSE mount, check the xattrs,
replace-brick with commit force.</div>

</div>
<div>Is all this still necessary? I'm running Gluster 5.6 on
CentOS 7 with a distribute–replicate volume.<br>

No, all these very steps are 'codified' into the `replace brick
commit force` command via
<a class="moz-txt-link-freetext" href="https://review.gluster.org/#/c/glusterfs/+/10076/">https://review.gluster.org/#/c/glusterfs/+/10076/</a> and
<a class="moz-txt-link-freetext" href="https://review.gluster.org/#/c/glusterfs/+/10448/">https://review.gluster.org/#/c/glusterfs/+/10448/</a>. You can see the
commit messages of these 2 patches for more details.<br>
<br>
You can play around with most of these commands in a 1 node setup if
you want to convince yourself that they work. There is no need to
form a cluster.<br>

Why don't you send a patch to update the doc for replace-brick? I'd
be happy to review it. <span class="moz-smiley-s3"><span>;-)</span></span><br>
