[Gluster-users] Split brain on directory?

I seem to have developed a split brain situation on a directory...  I
think.  The directory is a hierarchy that shouldn't exist, as it's
actually a hard link to the volume itself in the brick.  Here's what I'm

- Brick mount point (XFS): /mnt/gfs/wingu1/sdb1
- Volume: /mnt/gfs/wingu1/sdb1/homes

The FUSE mount for this volume (/home" shows a directory hierarchy
similar to the brick mount point itself, but it's not actually
accessible or deletable etc:

# ls /home/mnt/gfs/wingu1/sdb1/homes
ls: cannot access /home/mnt/gfs/wingu1/sdb1/homes: No such file or directory

This volume is replica 2, and if I look on the corresponding bricks,
only one of them has this structure.  This seems to be causing the
self-heal daemon to go bonkers, develop a case of inception, and crash:


Log truncated by quite a bit, as it's hundreds of lines of the same...

Is this split brain?  And would it be safe to just delete this erroneous
directory from the brick itself?

Gluster version is 3.5.1 on CentOS 6.5.
