## The script tests the logging of the quota in the bricks after reaching soft
## limit of the configured limit.
##
##  Steps:
##  1. Create and mount the volume
##  2. Enable quota and set the limit on 2 directories
##  3. Write some data to cross the limit
##  4. Grep the string expected in brick logs
##  5. Wait for 10 seconds (alert timeout is set to 10s)
##  6. Repeat 3 and 4.
##  7. Cleanup
