Abstract
A partition manager enables the dynamic creation, reconfiguration, and deletion of logical volumes as non-removable storage devices are connected, reconfigured, or disconnected in a computer system by assigning partitions on a connected device to volume managers which create the logical volumes, and by removing the assignment when the device is disconnected or reconfigured. The partition manager receives notification from the operating system of the arrival of new volume managers in a system. When new partitions are created on a non-removable storage device in the system by a device driver, the partition manager intercepts the partitions before they can be registered with the operating system. The partition manager queries each volume manager, in order of their arrival in the system, as to whether the volume manager handles a particular new partition and assigns control of the partition to the appropriate volume manager. The partition manager associates the partition with the appropriate volume manager in an in-memory partition manager database. The partition manager also removes a partition from the control of the associated volume manager and disassociates the partition from the …
