Sorry, that is not what I meant. The bricks that provide the c_glusterfs
volume need to support and have ACLs enabled as well. If you use XFS, it
should be enabled by default. But some other filesystems do not do that.

You have three different mountpoints:

 - /tmp/e: nfs
 - /tmp/a2: Gluster FUSE
 - whatever you use as bricks for c_glusterfs: XFS or something else?

HTH,
