           Summary: [Quota] : Inode quota spurious failure
           Product: GlusterFS

         Component: quota
          Severity: high
          Priority: medium

+++ This bug was initially created as a clone of Bug #1229297 +++

I did some analysis on this and found out below mentioned
log during the case of failure.

[2015-06-08 03:45:21.317352] I [MSGID: 115071]
[server-rpc-fops.c:1591:server_crea
te_cbk] 0-patchy-server: 203: CREATE /test_dir/test1.txt
(72fa9c7d-d4cd-474e-baae-
28dde9b15990/test1.txt) ==> (Disk quota exceeded) [Disk quota exceeded]

The test case which fails is "TEST_IN_LOOP touch $M0/test_dir/test$i.txt",
while creating a file "test1" (i.e i=1). This should not fail as "test1" is
the first file being created in the directory where quota limit is set.
The only possible explanation is that before creating the file "test1",
we delete all the files present in that directory, and that information
has not been updated by marker. Because of which the new file creation
fails thinking the quota limit is still exceeded.

The test case basically validates both the types of quota (size and inode).
The reason for this spurious failure might be because of the delay in
updating the information my marker. I will verify the same by inducing
some delay before the execution of above mentioned testcase.

    features/quota : Fix spurious failure

    Problem : Basically, in this test case a file is created
    which exceeds the quota limit. Once the limit is reached
    that file will be deleted. At the same moment we are
    testing inode-quota. It can so happen that before the
    marker updates the information related to deletion of
    file, a new file creation operation comes and sees that
    quota limit is still exceeded.

    Solution : Inducing a check to see if marker updation
    completed successfully.

    Updated all the test case which has the similar
    machanism and also moved the "usage" function
    to a common place "volume.rc"
