--- Comment #1 from George <george.lian at nokia.com> ---
Sorry, some code error in test code while call system call open
wrong in attachment: open(argv[1], O_CREAT|O_RDWR|S_IRUSR|S_IWUSR) 
should be          : open(argv[1], O_CREAT|O_RDWR,S_IRUSR|S_IWUSR)

But it still seems has some issue while the file access in client with root
privilege, in the brick, the file could be read , but in the client, the file
has no content at all while the really size is "120".

in sn-0 storage brick, the file could be access:
# hexdump testfile.39
0000000 3039 0000 0000 0000 d431 0000 0000 0000

0000020 7365 6674 6c69 2e65 3933 0000 0000 0000

But in mounted gluster fs in client, the file can't be read.

[root at mn-0:/mnt/test/a__2]
# hexdump testfile.39
[root at mn-0:/mnt/test/a__2]
# echo $?
0
[root at mn-0:/mnt/test/a__2]
# ls -l testfile.39
---------T 1 root root 120 Dec 28 07:16 testfile.39
[root at mn-0:/mnt/test/a__2]
