<p>I will summarize the procedure for removing a brick with
description.</p>
<p><br>
</p>
<p>1) start an add brick operation using gluster volume remov-brick
command. This command will mark the mentioned brick as a
decommissioned brick. Also, this will kick a process that will
start migrating data from the decommissioned brick to the other
bricks.</p>
<p>2) Once the migration is finished you can safely do a
remove-brick commit.</p>
<p>3) Or if you wish to stop the process and reset the
decommissioned brick, you can do remove-brick stop. This will not
migrate the data back to the decommissioned brick. It will stay in
the other bricks and the data will be still accessible, if you
want to have proper load balancing after this, you can start
rebalance process.<br>
</p>
4) If you wish to do an instant remove brick you can use force
option, which will not migrate data, hence your whole data in the
removed brick will be lost from mount point.<br>

<div class="yiv5393753197MsoNormal">We are using
Gluster 3.7.6 in a replica 2
distributed-replicate configuration. I am
wondering when we do a remove-brick with just
one brick pair will the data be moved off the
bricks once the status show complete and then
you do the commit? Also, if you start a
remove-brick process can you stop it? Is there
an abort or stop command or do you just don’t do
the commit?</div>
