[Gluster-users] split-brain files not shown in "gluster volume heal info split-brain" command

[Lakshmi Anusha]

Hello,

We are using glusterfs version 3.7.2.
There are few i/o errors reported during our testing and i/o errors are due
to split brain files.
We tried to find the split brain files with "gluster volume heal <vol> info
split-brain".
But strangely the command shows that the number of split brain files count
is zero.

>From the extended attributes, an entry split-brain seems to be appeared.
Since gfid is different for the original file and its replica.
Can you please let us know why the split-brain files are not shown in
"gluster volume heal <vol> info split-brain" command?
Kindly let us know if any known issue exists.

Thanks & Regards,
