RedoxFS

This is the default filesystem of Redox OS, inspired by ZFS and adapted to a microkernel architecture.

Redox had a read-only ZFS driver but it was abandoned because of the monolithic nature of ZFS that created problems with the Redox microkernel design.

(It's a replacement for TFS)

Current features:

  • Compatible with Redox and Linux (FUSE)
  • Copy-on-write
  • Data/metadata checksums
  • Transparent encryption
  • Standard Unix file attributes
  • File/directory size limit up to 193TiB (212TB)
  • File/directory quantity limit up to 4 billion per 193TiB (2^32 - 1 = 4294967295)
  • Disk encryption fully supported by the Redox bootloader, letting it load the kernel off an encrypted partition.
  • MIT licensed

Being MIT licensed, RedoxFS can be bundled on GPL-licensed operating systems (Linux, for example).

Tooling

RedoxFS tooling can be used to create, mount and edit contents of an .img file containing RedoxFS. It can be installed with:

cargo install redoxfs

If you found errors while installing it, make sure to install fuse3.

Create a disk

You can create an empty, non bootable RedoxFS by allocating an empty file with fallocate then run redoxfs-mkfs to initialize the whole image as RedoxFS.

fallocate -l 1G redox.img

redoxfs-mkfs redox.img

Mount a disk

To mount the disk, run redoxfs [image] [directory]:

mkdir ./redox-img

redoxfs redox.img ./redox-img

It will mount the disk using FUSE underneath.

Unmount

Unmount the disk using FUSE unmount binary:

fusermount3 ./redox-img
