A new file-system called FTRFS (Fault-Tolerant Radiation-Robust Filesystem) has been proposed for the Linux kernel via an RFC patch series. Designed for radiation-intensive environments like space and other harsh conditions, it features CRC32 data integrity checks on a per-block and per-inode basis, Reed-Solomon Forward Error Correction (FEC), and EDAC-compatible error tracking. Current implementation covers basic functionality, with FSCK support, extended attributes, SELinux support, and indirect block support for large files still planned. The proposal comes amid growing interest in space-based computing infrastructure in low-earth orbit.
