Linux Employees of Lawrence Livermore National Laboratory have ported Sun's/Oracle's ZFS natively to Linux. Linux already had a ZFS port in userspace via FUSE, since license incompatibilities between the CDDL and GPL prevent ZFS from becoming part of the Linux kernel. This project solves the licensing issue by distributing ZFS as a separate kernel module users will have to download and build for themselves.

RE[3]: brtfs

Member since:

RAID 5/6 support has not been checked in yet, nor has it really been made available for testing beyond the two devs working on it. Thus, it doesn't support RAID levels above 1 yet.

Nor does it really support pooled storage, as you still have to specify the harddrives that will be used for each filesystem when you create the filesystem. There's no pool management yet, just filesystem management.

So, like I said, btrfs is where zfs was 10 years ago. It's not a replacement for zfs in any way at this time.

Maybe in 5 years, it'll be where zfs is now. But it's not there yet.
