Still, could you please elaborate on "gfid split-brain"?<br>

Was the other file's gfid <span>d3def9e1-c6d0-4b7d-a322-b5019305182e?<br>
Could you check if this file exists in

fixed. But before that could you
please post the output of

<div>Hello.<br>

I've Gluster
3.5.2 on
Centos 6. A
primitive
replicated
volume, as
describe <a
moz-do-not-send="true"
href="https://www.digitalocean.com/community/tutorials/how-to-create-a-redundant-storage-pool-using-glusterfs-on-ubuntu-servers"
target="_blank">here</a>. I tried to simulate split-brain by temporarily
disconnecting
the nodes and
creating a
file with the
same name and
different
contents. That
worked.<br>
<br>
</div>
<div>The
question is,
how do I fix
it now? All
the tutorials
suggest
deleting the
file from one
of the nodes.
I can't do
that, it
reports
"Input/output
error". The
file won't
even show up
in "gluster
volume heal
gv00 info
split-brain".
That shows 0
entries.<br>
</div>

</span> The deletion
needs to happen on one
of the bricks, not
from the mount point.<br>
