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
