Quota : test case with creation of file larger than quota limit
If a limit is set and a file of size larger than limit is created then the file creation will stop when it will reach the limit. - Enable Quota - Create a directory from mount point - Set a limit of 10 MB on the directory - Set Quota soft-timeout and hard-timeout to 0 seconds - Create a file of size larger than the Quota limit eg. 20 MB file - Perform Quota list operation to check if all the fields are appropriate such as hard_limit, available_space, sl_exceeded, hl_execeeded, etc. Change-Id: I44d7e23e60589cbe022735e9b4b5f3bfd1b7458e Signed-off-by: Vinayak Papnoi <vpapnoi@redhat.com>
