When you delete, rename, or change the security style of a qtree, the quotas applied by Data ONTAP might change, depending on the current quotas being applied.
More information
How deleting a qtree affects tree quotas
When you delete a qtree, all quotas applicable to that qtree, whether they are explicit or derived, are no longer applied by Data ONTAP.
How renaming a qtree affects quotas When you rename a qtree, its ID does not change. As a result, all quotas applicable to the qtree continue to be applicable, without reinitializing quotas. However, before you reinitialize quotas, you must update the quota with the new qtree name to ensure that the quota continues to be applied for that qtree.
How changing the security style of a qtree affects user quotas
You can apply Access Control Lists (ACLs) on qtrees by using NTFS or mixed security styles, but not by using the UNIX security style. Therefore, changing the security style of a qtree might affect how quotas are calculated. You should always reinitialize quotas after you change the security style of a qtree.
