We discussed using the top bits of the chunk type field field to

Is there any sort of timeline for RAID5/6 support in btrfs? I
currently have 8 drives in a zfs-fuse RAIDZ2 (RAID6) configuration,
and I'd love to see how btrfs compares to that, once it's ready.
I think someone started doing RAID[56] (see threads "A start at
RAID[56] support" and perhaps "Factor out RAID6 algorithms into lib/".
Seems something is in the works.
By the way - how does FUSE ZFS work? Is it stable? Good performance?
We're using ZFS natively on Solaris 10 now, perhaps moving the storage
to opensolaris soon.
