US 2019/0102100 A1 · TECHNIQUES FOR MANAGING PARTITIONS ON A STORAGE DEVICE

Abstract

Disclosed herein are techniques for managing partitions on a storage device. A method can include (1) identifying a storage capacity of the storage device, (2) generating a first data structure that defines a first partition on the storage device, where the first partition consumes a first amount of the storage capacity, and (3) generating a second data structure that defines a second partition on the storage device, where the second partition consumes at least a portion of a remaining amount of the storage capacity relative to the first amount. In response to receiving a shrink request directed to the first partition, the method can further include (4) identifying a first utilized area within the first partition that will no longer be utilized as a result of the shrink request, and (5) updating first information in the first data structure to indicate that the first utilized area is unutilized.

A method for managing partitions on a storage device, the method comprising:

identifying a storage capacity of the storage device;
generating a first data structure that defines a first partition on the storage device, wherein the first partition spans a first amount of the storage capacity;
generating a second data structure that defines a second partition on the storage device, wherein the second partition spans at least a portion of a remaining amount of the storage capacity relative to the first amount;
and
in response to receiving a shrink request directed to the first partition:
identifying a first utilized area within the first partition that will no longer be utilized as a result of the shrink request, and
updating first information in the first data structure to indicate that the first utilized area is unutilized.

At least one non-transitory computer readable storage medium configured to store instructions that, when executed by at least one processor included in a computing device, cause the computing device to manage partitions on a storage device that is communicably coupled to the computing device, by carrying out steps that include:

identifying a storage capacity of the storage device;
generating a first data structure that defines a first partition on the storage device, wherein the first partition spans a first amount of the storage capacity;
generating a second data structure that defines a second partition on the storage device, wherein the second partition spans at least a portion of a remaining amount of the storage capacity relative to the first amount;
and
in response to receiving a shrink request directed to the first partition:
identifying a first utilized area within the first partition that will no longer be utilized as a result of the shrink request, and
updating first information in the first data structure to indicate that the first utilized area is unutilized.

A computing device configured to manage partitions on a storage device, the computing device comprising:

at least one processor;
and at least one memory storing instructions that, when executed by the at least one processor, cause the computing device to:
identifying a storage capacity of the storage device;
generating a first data structure that defines a first partition on the storage device, wherein the first partition spans a first amount of the storage capacity;
generating a second data structure that defines a second partition on the storage device, wherein the second partition spans at least a portion of a remaining amount of the storage capacity relative to the first amount;
and
in response to receiving a shrink request directed to the first partition:
identifying a first utilized area within the first partition that will no longer be utilized as a result of the shrink request, and
updating first information in the first data structure to indicate that the first utilized area is unutilized.
