<p>Can you please explain How we ended up in this scenario. I think
that will help to understand more about this scenarios and why
gluster recommend replica 3 or arbiter volume.</p>

<div>Hi Ludwig,<br>
<br>
</div>
There is no way to resolve gfid split-brains with type
mismatch. You have to do it manually by following the steps in
[1].<br>
</div>
<div>In case of type mismatch it is recommended to resolve it
manually. But for only gfid mismatch in 3.11 we have a way to<br>
</div>
<div>resolve it by using the *favorite-child-policy*.<br>
</div>
<div>Since the file is not important, you can go with deleting
that.<br>

<div dir="ltr">I am new to gluster but already like it. I
did a maintenance last week where I shutdown both nodes
(one after each others). I had many files that needed to
be healed after that. Everything worked well, except for 1
file. It is in split-brain, with 2 different GFID. I read
the documentation but it only covers the cases where the
GFID is the same on both bricks. BTW, I am running Gluster
3.10.
