<div dir="ltr"><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><br></div><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><br></div><div style="text-align:left">Regarding the patch to the documentation: absolutely! Let me just get my Gluster back in order after my confusing upgrade last month. :P</div><div style="text-align:left"><br></div><div style="text-align:left">Thanks,<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Jun 11, 2019 at 7:32 PM Ravishankar N <<a href="mailto:ravishankar@redhat.com">ravishankar@redhat.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<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documentation for replace-brick¹ was out of date.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

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="gmail-m_-8507537768089740775moz-smiley-s3"><span>;-)</span></span><br>
