You recipe doesn't work :-( If there is
difference between bricks directories
due to direct brick manipulation it
leads to problems.<br>
<br>
You have to execute "gluster volume heal
<volname> full" for triggering
full heal.<br>
<br>
</blockquote>
</span> yeah, but I need to know that I need
to execute it.<br>
any help from gluster or only external
script?<br>
<br>
<br>
</blockquote>
</div>
I guess it is not too difficult to set up
cron/systemd.timer to run this command once in a
while right?</div>
</div>
</blockquote>
<br>
</span> Too difficult? No. <br>
So you are suggesting to run heal full by cron? Right?<br>
Really, I don't know how much resources this full heal
may need in real installations.<br>
If not much- why self-heal doesn't call it?<span
class=""><br>
</span></div>
</blockquote>
<div><br>
</div>
<div>Because we don't expect people to touch the bricks. For
a corner case it doesn't make sense to keep doing full
filesystem scan. But we do provide the CLI for people who
want it.<br>

<br>
Well, why run heal every 10 minutes if no problems are expected?<br>
From your link:<br>
<h1><br>
</h1>
<p>The index heal is done:<br>
a) Every 600 seconds (can be changed via the <code>cluster.heal-timeout</code>
volume option)<br>
b) When it is explicitly triggered via the <code>gluster vol heal
<VOLNAME></code> command<br>
c) Whenever a replica brick that was down comes back up. <br>
</p>
<br>
As I can understand, this index heal runs once per volume, not on
specific node, this is why there is self-heal daemon,<br>
otherwise this can be achieved by cron. If I have node with cron
down, then I'll get no full heal, I can, definitely, run next full
heal on different node by cron :-)<br>

<br>
</span> Which compares bricks directories, and, if it
there is real need- it alerts me, I can run heal full
or, may be, just trigger files heal by reading some
files over fuse.<br>
Could you , please, tell me how heal full works and why
it is not part of self-heal process?<br>

Thank you!<br>
I think it will be wise to add full heal interval to self-heal
daemon.<br>
