I don't think this is possible. I'd like to what why do you want to use
use a root file system as a Gluster volume, what's your use case.
Technically this is impossible (wrt GlusterD) as we then have no way to
segregate the configuration data.

[Gluster-devel] Glusterfs as a root file system on the same node

[satish kondapalli]

Hi,

I want to mount  gluster volume as a root file system for my node.

Node will boot from network( only kernel and initrd images) but my root
file system has to be one of the gluster volume ( bricks of the volume are
on the disks which are attached to the same node).  Gluster configuration
files also part of the root file system.

Here i am facing chicken and egg problem.  Initially i thought to keep
glusterfs libs, binary in the initrd and start the gluster server as part
of initrd execution. But for mounting root file system (which is a gluster
volume), all the gluster configuration files are stored in the root file
system. My assumption is, without gluster configuration
files(/var/lib/glusterd/xx) gluster will not find any volumes.

Can someone help me on this?
