Quota Limits

Each quota entity has two limits associated with it. These are the Hard Limit, and the Soft Limit.

Parameter Description
Hard Limit

The Hard Limit is the absolute limit which file system space usage should not exceed. Any time the total allocated space is at or over the Hard Limit, all further allocations or write requests by the offending user or group will be denied.

Soft Limit

The Soft Limit is a lesser limit. When you exceed this limit (but not the Hard Limit), allocations are still permitted, but a warning will be written to your console. When the Soft Limit has been overrun for longer than the Total Grace Period, the Soft Limit becomes a Hard Limit and any further allocations or write requests are denied. When the usage again falls below the Soft Limit, allocation requests will again be serviced.

For performance reasons related to the distributed nature of StorNext, quota overruns are not only possible but likely. The overrun size depends upon a number of factors including the size of the allocation request(s) at the time of the quota overrun.

Note: Limits are not enforced against super user accounts.

Note: For all quota types, limits and usage values only apply to regular files, not directories, symlinks, or special device files.
