4.5.3. Keeping Quotas Accurate

If you enable quotas on your file system after a period of time when you have been running with quotas disabled, you should run the quotacheck command to create, check, and repair quota files. Additionally, you may want to run the quotacheck if you think your quota files may not be accurate, as may occur when a file system is not unmounted cleanly after a system crash.
For more information about the quotacheck command, see the quotacheck man page.

Note

Run quotacheck when the file system is relatively idle on all nodes because disk activity may affect the computed quota values.
