EROFS 文件系统是一个 Linux 只读文件系统,目的是在保证端到端性能的前提下节省额外的存储空间,这一文件系统从 Linux 4.19 开始得到了正式升级。此前,该文件系统主要用于嵌入式设备,但是,我们发现对于容器用例也有迫切的只读高性能文件系统需求。本主题将详细介绍我们正在为此种新场景开发的新特性。
EROFS filesystem is a Linux read-only file system in order to save extra storage space with guaranteed end-to-end performance, which was formally upstreamed since Linux 4.19. Previously it was mainly used for embedded devices, however, we found serious read-only high-performance filesystem requirement for container use cases as well. This topic will give a detailed introduction on what new features we're working for such new scenario.
