Hi, 1. AFR as such doesn't need any namespace brick, but with current version of GlusterFS, for unify namespace is the single point of failure. Hence, to give redundancy to unify, one can use AFR. 2. posix-locks translator is used when one needs support of 'fcntl()' and 'flock()' syscalls from their GlusterFS filesystem. Hope your doubts are clear.
