Right... I deleted it and now all appears to be fine.
Still, could you please elaborate on "gfid split-brain"?
Could you go through
https://github.com/gluster/glusterfs/blob/master/doc/debugging/split-brain.md
Let us know if you would like something to be more clearer and we can
add that and improve the document.

Any insight?
Was the other file's gfid d3def9e1-c6d0-4b7d-a322-b5019305182e?
Could you check if this file exists in <brick>/.glusterfs/d3/de/
When a file is deleted this file also needs to be deleted if there
are no more hardlinks to the file

What's a gfid split-brain and how is it different from
"normal" split-brain?
I accessed the file with stat, but "heal info" still shows
"Number of entries: 1"

Ahh, thank you, now I get it. I deleted it on one node
and it replicated to another one. Now I get the
following output:
[root@gluster1 var]# gluster volume heal gv01 info
Brick gluster1:/home/gluster/gv01/
<gfid:d3def9e1-c6d0-4b7d-a322-b5019305182e>
Number of entries: 1
Brick gluster2:/home/gluster/gv01/
Number of entries: 0
Is it normal? Why the number of entries isn't reset to 0?
If you access the file using ls/stat etc, it will be
fixed. But before that could you please post the output
of 'getfattr -d -m. -e hex file/path/in/backend/brick'
and 'getfattr -d -m. -e hex
parent/dir/to/file/path/in/backend/brick'

And why wouldn't the file show up in split-brain before,
anyway?
Gfid split-brains are not shown in heal-info-split-brain yet.

Hello.
I've Gluster 3.5.2 on Centos 6. A primitive
replicated volume, as describe here
<https://www.digitalocean.com/community/tutorials/how-to-create-a-redundant-storage-pool-using-glusterfs-on-ubuntu-servers>.
I tried to simulate split-brain by temporarily
disconnecting the nodes and creating a file with
the same name and different contents. That worked.
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.
The deletion needs to happen on one of the bricks,
not from the mount point.
Pranith
I can see the file in "gluster volume heal gv00
info heal-failed", though.
