"A new version of the next-generation copy-on-write snapshotting GPL filesystem for Linux is out: bcachefs 1.37.0 appeared just yesterday as we write. This release includes support for the forthcoming Linux kernel 7.0. It is expected next month - the latest release candidate, 7.0-rc4, appeared the same day as the new bcachefs release."
"This release has improved erasure coding, faster recovery from unsafe shutdowns, multi-device filesystems are quicker, and more. The notes in the Git commit mention a new version of the bcachefs manual, which creator Kent Overstreet calls its Principles of Operation [PDF] - P.o.O. for short."
"COW snapshots are an important feature in modern OSes - the FreeBSD folks are justly proud of their built-in native support for the ZFS filesystem from Solaris. OpenZFS works fine with Linux, but it can't be merged into the Linux kernel because Sun's license is incompatible with the Linux's GPL."
bcachefs 1.37.0 has been released with support for the forthcoming Linux kernel 7.0, expected next month. The filesystem, now developed outside the kernel as a DKMS module, features improved erasure coding, faster recovery from unsafe shutdowns, and enhanced multi-device filesystem performance. The project includes an expanded 100-page Principles of Operation manual. Simultaneously, Linux distributions are gaining support for Apple's APFS disk format. Copy-on-write snapshot capabilities remain central to modern filesystem design, with bcachefs positioning itself as a GPL alternative to proprietary solutions like ZFS, which cannot be merged into Linux due to licensing incompatibilities.
