[Gluster-users] Volume creation fails with "prefix of it is already part of a volume"

[Anand Avati]

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 of
your data.

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