If you no longer use a NAS file system, you can delete it to prevent additional costs.
After you delete a file system, the data stored in the file system is deleted and cannot be restored. Before you delete a file system, make sure that you no longer need to use the data in the file system. If you need to continue to use the data in the file system, migrate the data in advance. For more information about how to migrate data, see Usage notes.
Prerequisites
If you are a RAM user, make sure that the RAM user has full access to the file system. For more information, see Example 1: Grant a RAM user the permissions on a NAS file system.
Precautions
If the billing method of an Extreme NAS file system is subscription, you cannot delete the file system by using the console or by calling API operations. If you want to delete an Extreme NAS file system whose billing method is subscription, contact NAS technical support.
Procedure
Log on to the NAS console
In the left-side navigation pane, choose File System > File System List.
In the top navigation bar, select a region.
On the File System List page, find the file system that you want to delete, and choose
> Delete in the Actions column. In the Delete File System dialog box, confirm the name of the file system and click Delete.
If a General-purpose NAS file system has related resources or configurations, such as mount targets, lifecycle policies, log dump tasks, data retrieval tasks, and the recycle bin feature, you must clear these resources and configurations in the Delete File System dialog box, and then click Delete.
NoteWhen you delete a file system, you do not need to delete the associated permission group. For more information about how to delete a permission group and custom rules in the permission group, see Manage a permission group.
You cannot delete or modify the default permission group.
