LVM3: The Next Generation of Logical Volume Management

LVM3 is the successor to the widely used Linux Logical Volume Manager, LVM2, aiming to address some of its limitations and introduce improvements for performance, features, and maintainability. It is designed with a fresh approach to the core mechanisms, aiming for a cleaner architecture and leveraging modern kernel capabilities.

Key Goals and Improvements:

• Improved Performance: LVM3 seeks to offer significant performance enhancements through better parallelization, reduced overhead, and optimized data structures.
• Enhanced Scalability: The architecture aims to scale more efficiently with larger storage systems and a greater number of logical volumes.
• Simplified Administration: LVM3 endeavors to make the management of logical volumes simpler and more intuitive, potentially through improved command-line tools and APIs.
• Modernized Codebase: The code is being rewritten with a modern design, which should lead to easier maintenance, bug fixing, and feature additions.
• Metadata Format: LVM3 is expected to use a new metadata format that allows for greater flexibility and efficiency.
• Kernel Integration: Deep integration with the Linux kernel is expected to utilize the latest features for improved storage management.
• Thin Provisioning: More efficient and scalable thin provisioning capabilities.
• Snapshots: Enhanced snapshotting features, potentially with better performance and space efficiency.
• RAID Support: Improved RAID integration for data protection and performance.

Status:

As a developing project, LVM3 is still undergoing active development. While offering the promise of significant improvements, it is essential to check on current status and consider stability before implementing into a production environment.
