Note: The information below assumes you have the Quotas feature enabled on your file system(s). See Quotas in Advanced Parameters > Features Tab.
The quota system provides a means for limiting the amount of disk storage consumed on a per user or per group basis across an entire file system or within a designated directory hierarchy. Quota limits apply to the space consumed by disk-block allocations for a user or group, which is not equal to the sum of their file sizes. Disk-block allocations can be less than the file size if the file is sparse, or more if the file system has allocated extra sequential blocks for the efficiency of anticipated future writes.
WARNING: If you enable quotas on an existing file system, the file system becomes unavailable while the changes are applied.
For more information about quotas, see the StorNext User's Guide.

As soon as the Soft Limit quota value has been exceeded, you have the configured Total Grace Period amount of time to free up space to return your usage under the Soft Limit quota value. |
