To makes things clear about how glusterfs understand 'type' of a volume
defined in the vol file.
GlusterFS does try to open a shared library file located at
"${XLATOR_DIR}/<given/type/in-vol-file>.so". Now, if you look at the
directory '${XLATOR_DIR}/features/', you can find that posix-locks.so is a
symlink to 'locks.so'. Hence they both are actually same library (ie, same
type in volume file).
Other symlinks used are
cluster/dht -> cluster/distribute
cluster/afr -> cluster/replicate
-----
Now coming to locks issues, yes, we did fix some issues with 'flock()' in
recent 3.0.x version. Please use 3.0.2+ version, and let us know how it
goes.
