What I don't understand is the lack of RAID-5 equivalent, which ZFS does provide (via raidz1 or raidz2).

RAID 0, RAID 1, or RAID 10. So I'm forced to have an evenly divisible number of disks? Who has a 5 disk array?!?!? Oh wait, right, those servers with 6 disks where 1 is dedicated to the OS... "Oops".

I like following Linux, especially Btrfs's evolution, but I think this will be a big show-stopper unless a RAID-5 equivalent is added.I read the article to mean it hasn't been implemented yet.

At this time, it can do RAID-0, RAID-1, RAID-10 but will be adding other RAID levels.

Agreed on the rest.

Some of the comments on the article are dead on, by the way. I'm not sure the author actually took the time to read about ZFS, how it works, or how to administrate it. The fact that it's a filesystem *and* an LVM equivalent in one, is one of many reasons ZFS is so beautiful. Linux's LVM is... well, let's just say I'd rather shoot myself in the face.

The founder of btrfs talks about features, terabyte raid arrays and comparisons with ZFS.

Following up our introductory article on “Butter FS” (See Linux Don’t Need No Stinkin’ ZFS: BTRFS Intro & Benchmarks - ZFS may be locked into the Solaris operating system but “Butter FS” is on the horizon and it’s boasting more features and better performance.), Jeff Layton talked with Chris Mason, Director of Linux Kernel Engineering at Oracle and the founder and lead developer of Btrfs.
