Embodiment Construction

[0021] Quickly and efficiently storing and retrieving large amounts of data may be required using limited amounts of processing power, bandwidth, and memory. In some examples, memory management techniques can be used to create a virtual memory system that can allow memory to appear to a process or task as a large, contiguous address space. However, those addresses (ie, virtual memory addresses) may or may not correspond to consecutive physical memory addresses.

[0022] In a virtual memory system, translation tables may be used to translate virtual memory addresses into corresponding physical memory addresses. In some such examples, each entry of the translation table may enable the virtual memory system to associate a virtual memory address with a physical memory address.

[0023] Additionally, data compression techniques can be used to maximize storage capacity. In some examples, data may be compressed before being written to memory. Data compression may involve transferr...

Abstract

Examples include repairing a volume while it is online. In some examples, a request to access a compressed page including compressed data and compressed metadata is received, errors are identified in the compressed metadata or compressed data, and based on the errors and the request, are processed while the volume is online Bug fixes.

Description

technical field [0001] The present disclosure generally relates to memory systems. Background technique [0002] The task of storage solutions is to store and retrieve large amounts of data quickly and efficiently with limited amounts of processing power, bandwidth and memory. Some storage solutions can compress data to maximize storage capacity. Metadata can be used to facilitate discovery and retrieval of compressed data. In some instances, errors may develop in compressed data or metadata. Contents of the invention [0003] According to one embodiment of the present disclosure, a machine-readable storage medium encoded with instructions executable by a processing resource to repair a volume while the volume is online is provided, the machine-readable storage medium Instructions are included for: receiving a request to access a compressed page, wherein the compressed page includes compressed data and compressed metadata; identifying errors in the compressed metadata o...
