Meet Linux's Newest File-System: Bcachefs

Posted by Soulskill on Friday August 21, 2015 @08:46AM from the my-compliments-to-the-bcachefs dept.

An anonymous reader writes: Bcachefs is a new open-source file-system derived from the bcache Linux kernel block layer cache. Bcachefs was announced by Kent Overstreet, the lead Bcache author. Bcachefs hopes to provide performance like XFS/EXT4 while having features similar to Btrfs and ZFS. The bachefs on-disk format hasn't yet been finalized and the code isn't yet ready for the Linux kernel. That said, initial performance results are okay and "It probably won't eat your data — but no promises." Features so far for Bcachefs are support for multiple devices, built-in caching/tiering, CRC32C checksumming, and Zlib transparent compression. Support for snapshots is to be worked on.

Mrs Overstreet? by TechyImmigrant · 2015-08-21 08:49 · Score: 4, Funny

If there's a Mrs Overstreet, she needs to be careful. Linux FS programmers have a bit of a history.

Re:Why? What advantages does this have over ZFS? by Anonymous Coward · 2015-08-21 09:34 · Score: 5, Funny

Wrong. If you have enough RAM (about 4x what you would normally estimate you need) and a fast enough CPU and keep your storage pool small, then it is not a hog. I wish people here would stop trying to mislead us about ZFS.
