Thanks for the very good summary.

So... In very brief summary, btrfs raid5 is very much a work in progress.

Question: Is the raid5 going to be seamlessly part of the
error-correcting raids whereby raid5, raid6,
raid-with-n-redundant-drives are all coded as one configurable raid?

Also (second question): What happened to the raid naming scheme that
better described the btrfs-style of raid by explicitly numbering the
number of devices used for mirroring, striping, and error-correction?

Thanks,
Martin
