Doc Type: Bug Fix
Doc Text:
When the quota limit is set to zero, quota enforcement is disabled, rather than enforcing a quota limit of 0 and preventing any writes. To prevent confusion when using this option, numbers smaller than or equal to zero are no longer valid values.

Comment 2 Vijaikumar Mallikarjuna 2015-12-30 01:07:13 EST
Quota enforcer assumes that if hard-limit is 0, then there is no limit set.
1) don't allow user to set limit to 0
2) quota enforcer should treat hard-limit 0 is a valid limit set
