Short announcement, because I'm in the process of moving - but I wanted to get this out there because the code is up and I think it's reasonably stable right now.
Bcachefs is a posix filesystem that I've been working towards for - well, quite awhile now: it's intended as a competitor/replacement for ext4/xfs/btrfs. Current features - multiple devices - replication - tiering - data checksumming and compression (zlib only; also the code doesn't work with tiering yet) - most of the normal posix fs features (no fallocate or quotas yet) Planned features: - snapshots! - erasure coding - more There will be a longer announcement on LKML/linux-fs in the near future (after I'm finished moving) - but I'd like to get it a bit more testing from a wider audience first, if possible. You need the bcache-dev branch, and the new bcache tools - be warned, this code is _not_ compatible with the upstream bcache on disk format: $ git clone -b bcache-dev http://evilpiepirate.org/git/linux-bcache.git $ git clone -b dev http://evilpiepirate.org/git/bcache-tools.git Then do the usual compiling... # bcacheadm format -C /dev/sda1 # mount /dev/sda1 /mnt The usual caveats apply - it might eat your data, the on disk format has _not_ been stabilized yet, etc. But it's been reasonably stable for me, and passes all but 2-3 of the supported xfstests. Try it out and let me know how it goes! Also, programmers please check out the bcache guide - feedback is appreciated: http://bcache.evilpiepirate.org/BcacheGuide/ Thanks! -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
