EXOFS (formerly known as OSDFS) is an object-based file system implemented on top of an external object store. Its name stands for "EXtended Object File System" referring to its use of ext2-based metadata and object storage devices.
Exofs was originally developed by Avishay Traeger for IBM HRL and was originally based on the ext2 file system. [1] Since 2008, Panasas develops and maintains Exofs on open-osd.org.
Exofs has been included in the mainline Linux kernel since version 2.6.30-rc1, [2] but no Linux distribution implemented this with a utility for making file systems in exofs for the current kernel line. It was removed in version 5.1-rc1. [3]
