基于Fuse的用户态文件系统的设计

The design of a filesystem in userspace using Fuse

现有的文件系统大都运行在内核态下,与内核紧密结合,导致难以对其进行功能上的扩展。针对内核文件系统的这个问题,本文提出了一个基于Fuse框架实现的用户级文件系统dbfuse。一方面将文件系统从内核态中解放出来;另一方面使用数据库技术有效地保证文件系统数据的完整性和安全性,给数据共享带来的方便。

Nowadays, most of the filesystems run in kernel-level, integrated with the Operating System, and they are hard to be extended in function. To solve this problem, we designed a userspace filesystem name dbfuse using Fuse framework here in the article. This filesystem runs in user-level, and bases on database technology to ensure the integrality and the safety of the data in the filesystem, as well as the convenience of data sharing.
