If you uninstall Tools from a Linux ECS in a non-PVOPS system, data disks cannot be identified. In such a case, you can create a new ECS and attach the data disks of the original ECS to the new ECS and view information about the data disks. The procedure is as follows:
Ensure that the new ECS is located in the same AZ and has the same parameter settings as the original ECS.
Manually refresh the Elastic Cloud Server page. The original ECS is stopped once the Status changes to Stopped.
The ECSs running certain OSs support online data disk detaching. If your OS supports this feature, you can detach data disks from the running ECS.
Manually refresh the Elastic Volume Service page. The data disk is detached from the original ECS once the Status changes to Available.
Manually refresh the EVS list. The data disk is attached to the new ECS once the Status value changes to In-use. You can then log in to the management console and view information about the data disk of the new ECS.
