Detaching a Block Volume
On Compute Cloud@Customer, when an instance no longer needs access to a volume, you can detach the volume from the instance without affecting the volume's data.
If you later reattach the detached volume, the volume might be associated with a different device name and the instance operating system might not recognize the volume.
Prerequisites
-
Perform administrative tasks to remove any dependencies that any instances have for the block volume.
For example, ensure that no applications are accessing the volume. Unmount the volume and remove it from the
/etc/fstabfile, and so on.
