Makes some sense. Yes, I meant "make a backup and delete", rather than
just delete.
If I may suggest, putting that debug link somewhere more visible would
be be good, too. I wouldn't find without your help.
Justin, where shall we put the doc?

Thank you for the assistance.

I don't understand why there's such a complicated process to

need and delete another one.
If the file needs to be deleted the whole file needs to be copied
which is fine for small files but for big files like VM images it
takes less time if the file already exists and it syncs only the
parts of files that are different from the good copy.
One more reason is if the parent directory from which the file is
deleted from is the source then self-heal will delete the file
from other directory rather than creating it. SO instead of
deleting the file may be it is a better practise to make a copy of
the file somewhere and delete it. We shall update the document as
well with this new information. Thanks for the feedback. In 3.7 it
is going to be simplified. We are giving a command to fix the
split-brains where the user gets to choose the file and it will do
the rest.

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.

Was the other file's gfid

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

Ahh, thank you, now I get it. I deleted it on

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'
Pranith
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.
