Not yet, but I'm pretty sure it's on the roadmap.

- Chris.

Is it possible to view the raid levels of data and meta data for an
existing btrfs filesystem?  It's easy to pick them when creating the
system, but I couldn't find any way to view them afterwards.

   "btrfs f df" will show them, except for few kernel releases when the ioctl()
was broken.


I guess it's time to update my System Rescue CD to a version with the btrfs command rather than just btrfsctl etc. Thanks!
