Right... I deleted it and now all appears to be fine.

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

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"

[root@gluster1 gluster]# getfattr -d -m. -e hex gv01/123

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. 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.

I can see the file in "gluster volume heal gv00 info heal-failed", though.
