<div>Dear Ravi,</div>
<div><br>
</div>
<div>Thanks for the confirmation—I replaced a brick in a volume
last night and by the morning I see that Gluster has
replicated data there, though I don't have any indication of
its progress. The `gluster v heal volume info` and `gluster v
heal volume info split-brain` are all looking good so I guess
that's enough of an indication.<br>
</div>
</div>

Yes, right now, heal info showing no files is the indication. A new
command for pending heal time estimation is something that is being
worked upon. See <a class="moz-txt-link-freetext" href="https://github.com/gluster/glusterfs/issues/643">https://github.com/gluster/glusterfs/issues/643</a> <br>

<div>One question, though. Immediately after I replaced the
brick I checked `gluster v status volume` and I saw the
following:</div>
<div><br>
</div>
<div>Task Status of Volume volume<br>
------------------------------------------------------------------------------<br>
Task : Rebalance <br>
ID : a890e99c-5715-4bc1-80ee-c28490612135<br>
Status : not started</div>
<div><br>
</div>
<div>I did not initiate a rebalance, so it's strange to see it
there. Is Gluster hinting that I should start a rebalance? If
a rebalance is "not started" shouldn't Gluster just not show
it at all?<br>
</div>
</div>
</blockquote>
<p>`replace-brick` should not show rebalance status. Not sure why
you're seeing it. Adding Nithya for help.<br>

<p>Great. Please send the PR for the
<a class="moz-txt-link-freetext" href="https://github.com/gluster/glusterdocs/">https://github.com/gluster/glusterdocs/</a> project. I think
docs/Administrator Guide/Managing Volumes.md is the file that
needs to be updated.</p>

<div>Dear list,</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that the documentation for replace-brick¹ was out of
date.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><br>
</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

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
