Event ID 9 — Quota Minifilter Driver Integrity

Applies To: Windows Server 2008 R2

For quota enforcement to work, the quota minifilter driver must be working properly, and it must be correctly attached to the volume. If the quota minifilter driver is experiencing problems, quota scans might fail, and updated quota usage information of volumes and folders will not be available. If the driver cannot attach to the volume, quotas cannot be enforced on that volume.

Event Details

Product: Windows Operating System
ID: 9
Source: quota
Version: 6.1
Message: The quota minifilter driver was successfully attached to volume "%2 (%3)" but the quota usage information is possibly out of date, and the volume will be rescanned. This can typically occur as a result of a system crash, quota configuration backup/restore, and volume failover in a cluster. Once the scan completes quotas will function properly.


This is a normal condition. No further action is required.
