Yesterday when I was testing, both the exports (one on glusterfs fuse mount and another on ext4) had same fsid. So when I was trying to mount and access the share on ext4, it had redirected to glusterfs fuse mount and hence the test failed. I re-checked with ext4 and I do not see any failures. So probably then we need to put a fix in glusterfs to bypass this check for file owner during OPEN. @Omar, Could you please file a bug against glusterfs component in RH bugzilla [1] for the same?
