It is always advised to "make uninstall" with the same source you used
for installation. In case if you did not have the original source,
remove the glusterfs files and directories manually (/etc/glusterfs,
/usr/lib/glusterfs, /usr/lib/libglusterfs*, /usr/share/doc/glusterfs).
This rule applies to most software compiled installed from source.

More info...

In GlusterFS-1.2, translators didn't have versioning support. So when
users overwrote with a newer version with incompatible translator ABI,
they experienced obscure segfaults. GlusterFS-1.3 has translators
installed under a versioned directory to protect such errors.

Even if you "make uninstall" with the newer source, Makefile will not
know how to remove files that were installed by the older versions but
removed in newer source. It will lead to stale files.
