value
After you select this check box, if data disks have been attached to the specified ECS instances and the file system of the last data disk is uninitialized, the system automatically formats the last data disk to ext4 and mounts the data disk to /var/lib/docker and /var/lib/kubelet. The original data on the disk will be cleared. Make sure that you back up data in advance. If no data disk is mounted on the ECS instance, no new data disk will be purchased. Default is false.
