Note: Disk capacity can only be increased, not decreased. After successfully increasing the capacity, you need to go into the Instance's operating system to expand the corresponding partition.

Delete a Disk​

You can delete a disk even while the Instance is running.

Warning: Deleting a disk will permanently erase all data on that disk. This operation cannot be undone. Back up your data before deleting.

Steps to delete a disk:

  1. In the Storage Disk tab, find the disk to delete.

You can create a Snapshot for a disk directly from the Storage Disk tab.

  4. Click Confirm.

Create Snapshot from the Storage Disk tab

Snapshots are created asynchronously. After completion, you can view the Snapshot in the Snapshot module.

Note: A disk Snapshot only saves the state of a specific disk, unlike a full Instance Snapshot.

  1. In the Storage Disk tab, find the disk to tag.
  2. Open the action menu and select Manage Tags.
