DISK PARTITION STITCHING AND REBALANCING USING A PARTITION TABLE

摘要

Embodiments are directed to dynamically changing partitions size for a partition in a storage device and to transferring storage space between partitions in a storage device. A computer system identifies portions of free space on a storage device, where the storage device has at least one partition whose offset and length are stored in a partition table. The computer system determines where the identified free space is located relative to other storage locations on the storage device. The computer system further determines that the partition is to be dynamically resized to a new size which is specified by one or more offset and length values, and based on where the identified free space is located, dynamically transforms the partition into a logical partition, and resizes the logical partition, the logical partition's offset and length values being updated in the partition table to include the new specified offset and length values.

1. At a computer system including at least one processor, a computer-implemented method for dynamically changing partitions size for a partition in a storage device, the method comprising:
identifying one or more portions of free space on the storage device, the storage device having at least one partition whose offset and length are stored in a partition table; determining where the identified free space is located relative to other storage locations on the storage device; determining that the partition is to be dynamically resized to a new size, the new size being specified by offset and length values; and based on where the identified free space is located, dynamically transforming the partition into a logical partition, and resizing the logical partition, the logical partition's offset and length values being updated in the partition table to include the new specified offset and length values.
