Automatically recreating lost storage volumes

Abstract:

A computing device, a non-transitory computer readable storage medium, and a method are provided for automatically recreating lost storage volumes. A volume command including volume metadata associated with a storage volume of an SCM storage device is received. The volume metadata is stored at another storage device that is less volatile than the SCM storage device. The storage volume is configured in accordance with the volume command including forwarding the volume command to an SCM device driver. A notification of a persistence loss at the SCM storage device is received subsequent to forwarding the volume command. The volume metadata is retrieved from the other storage device subsequent to receiving notification of the persistence loss. The storage volume is automatically re-configured in accordance with the volume command including submitting the retrieved volume metadata to the SCM device driver.
