Deleting a file system deletes the data in the file system, and the data cannot be recovered. ## Before you delete * The data that you want to keep has been backed up or migrated. * The file system is not used by running training, inference, or data processing jobs. * You understand that data cannot be recovered after deletion. ## Unmount the file system Before you delete a file system, unmount it from CES instances or CKS cluster nodes. If you do not unmount the file system first, subsequent commands such as `df` on compute nodes may hang because the file system cannot be found. 1. Log on to the console and go to **GPFS**. 2. Choose **Unmount**. 3. Select the CES instance on which the file system is mounted and enter the mount path. 4. Confirm the operation and complete the subsequent unmount steps. Unmount GPFS ## Delete the file system 1. Log on to the console and go to **GPFS**. 2. Find the file system that you want to delete, choose **Delete**, and follow the on-screen prompts to complete the operation. ## Impact after deletion | Impact | Description | | ----------------------------- | ----------------------------------------------------------------------------------------------------------- | | Data cannot be recovered | The data in the file system is deleted and cannot be recovered. | | Access is interrupted | Compute nodes that have mounted the file system can no longer access data in it. | | Mount status becomes abnormal | If the file system is not unmounted before deletion, the mount status on compute nodes may become abnormal. | If the file system fails to be deleted, record the error message and contact support.
