Abstract
The present disclosure is directed to seamless access to a common physical disk in an AMP system without an external hypervisor, and includes one or more processors and one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the system to perform operations including instantiating, by a first instance, a second instance during a system upgrade, creating, in the first instance, a first disk abstraction for a block device of a physical disk, and attaching the block device under the first disk abstraction. The operations further include providing the second instance network-based access to the physical disk using the first disk abstraction of the first instance during the system upgrade.
