<div>I'm fairly new to gluster and quite happy with it. We are
using it in an OVirt </div>
<div>environment that stores <span style="font-size: 10pt;">its
VM images </span><span style="font-size: 10pt;">in the
gluster. Setup is as follows and</span></div>
<div>
<div style="font-size: 13.3333px;"><span style="font-size:
10pt;">Clients mount the volume with gluster native fuse
protocol. </span></div>

<div><span style="font-size: 10pt;"><br>
</span></div>
<div><span style="font-size: 10pt;">3 storage nodes: Centos 7,
Gluster 3.8.12 (managed by me), 2 bricks each</span></div>
<div><span style="font-size: 10pt;">5 virtualization nodes:
Centos 7, Gluster 3.8.12 (managed by OVirt engine)</span></div>
<div><br>
</div>
<div>After todays reboot of one of the storage nodes the
recovery did not finish</div>
<div>successfully. The state of one brick remained in:</div>
<div><br>
</div>
<div>
<div>[root@cfiler301 dom_md]# gluster volume heal gluster1
info</div>
<div><span style="font-size: 10pt;">...</span></div>

<div>The above file is used by sanlock runing on the OVirt nodes
to <span style="font-size: 10pt;">handle VM </span></div>
<div><span style="font-size: 10pt;">image locking. </span><span
style="font-size: 13.3333px;">Issuing a manual heal with
"gluster volume heal gluster1" fixed </span></div>
<div><span style="font-size: 13.3333px;">the problem </span><span
style="font-size: 13.3333px;">but the unsynced entry
reappeared a few seconds later. </span></div>
<div><span style="font-size: 13.3333px;"><br>
</span></div>
<div><span style="font-size: 13.3333px;">My question: Should
this situation be recovered automatically and if yes</span></div>
<div><span style="font-size: 13.3333px;">what might be the
culprit?</span></div>

We have had this observed by our QE guys while testing too, but in
all cases, there was an intermittent disconnect from the fuse mount
to the bricks, leading to the 'ids' file needing heal (and being
healed on reconnect) again and again.<br>
Perhaps you should check if and why the mount is getting
disconnected from the bricks.<br>
