<div>Client-side heals are heals that happen from the GlusterFS
client, as part of LOOKUP, sometimes even READ, [F]STAT, etc.</div>
<div>You can tell when a client did a heal if a corresponding
log message appears in that client's log file (usually the
ones with MSGID: 108026, although name heals aren't logged).<br>
</div>
<div>They are enabled by default.<br>
To disable entry heal from clients for instance, you do
#gluster volume set <VOL> cluster.entry-self-heal off<br>
</div>
<div>To disable data self-heal from clients, you do #gluster
volume set <VOL> cluster.data-self-heal off<br>
</div>
<div><br>
</div>
<div>If you want to prevent the client from doing self-heal
altogether, you disable all three forms of client healing:
data-self-heal, entry-self-heal and metadata-self-heal.<br>
</div>
<div><br>
</div>
<div>Server side heals are heals that are performed by the
self-heal daemon. You will see log messages with MSGID: 108026
in glustershd.log when the self-heal-daemon performs a heal.<br>
</div>
<div>Server side heals happen in the following cases:<br>
</div>
<div>1) when you execute #gluster volume heal <VOL> full<br>
</div>
<div>2) when you execute #gluster volume heal <VOL><br>
</div>
<div>3) when a brick that was previously down comes back up.<br>
</div>
<div><br>
</div>
<div>To disable server side heal, you need to disable the
self-heal-daemon. You can do that with #gluster volume set
<VOL> cluster.self-heal-daemon off<br>
</div>
<div><br>

Will do. Wasn't aware there were different types of healing -
is there <br>
client and server side heals? are there any docs on this?<br>
