  Failed tests:  164-165

The failure happens because in the line 82 the getfattr command to get the value of the xattr trusted.pgfid.<gfid> each line fails and it still prints the output of 2 lines (i.e. both the xattrs, instead of the xattr that correspond to the file in interest)

getfattr -m "trusted.pgfid.*" -de hex /d/backends/brick/dir2/file2 2>&1 | grep "trusted.pgfid" | cut -d$'\n' -f 1 | cut -d'=' -f2
0x00000001
0x00000001
[root@hp-dl380pgen8-02-vm-10 gluster-gerrit]# getfattr -m "trusted.pgfid.*" -de hex /d/backends/brick/dir2/file2 2>&1 | grep "trusted.pgfid" | cut -d$'\n' -f 1
trusted.pgfid.1373485a-2780-4101-96ba-e5f4a63005cd=0x00000001
trusted.pgfid.e7180d50-89f4-4624-b4e3-408327fa695b=0x00000001



After some investigation found the below FIX:

The following for loop (which makes use of "awk -v n=$i 'NR==n'" will print only one line at a time (1st line for 1st iteration of the for loop and 2nd line for the 2nd iteration of the for loop)

for i in $(seq 1 2) ; do getfattr -m "trusted.pgfid.*" -de hex /d/backends/brick/dir$i/file$i 2>&1 | grep "trusted.pgfid"  | awk -v n=$i 'NR==n'; done
trusted.pgfid.1373485a-2780-4101-96ba-e5f4a63005cd=0x00000001
trusted.pgfid.e7180d50-89f4-4624-b4e3-408327fa695b=0x00000001

With the above change all the tests passed from this test case.
