HI Anand,

As Daniel mentioned already, I also tried to create a volume with only bric=
k on separate nodes, i.e. # gluster volume create vol_icclab transport tcp =
gluster-node4.test:/mnt/brick1/vol_icclab gluster-node1.test:/mnt/brick1/vo=
l_icclab, but I still get the same error.

Thanks,

This is intentional behavior. We specifically brought this because creating=
 volumes with directories which are subdirectories of other bricks, or if a=
 subdirectory belongs to another brick can result in dangerous corruption o=
f your data.

Please create volumes with brick directories which are cleanly separate in =
the namespace.

Thanks Daniel.

I'm indeed running Gluster 3.4 on CentOS 6.4.

I've tried your suggestion, it does work for me too, but it's not an
optimal solution.

Maybe someone could shed some light on this behaviour?

Thanks,
