Yes - but not terribly interested in doing that on linux. I do appreciate that it can be done, but still lacks raid-z reshaping, which means it isn't quite flexible enough. > On 02/24/12 18:26, Duncan wrote: >> FWIW, in the rare event it breaks revdep-rebuild or the underlying >> rebuilding itself, I rely on my long set FEATURES=buildpkg and >> emerge -K.

That would be the former. I'm QUITE aware of its stability. I've played around with it on a VM - I posted on my blog an experience with it around a year ago as well. It has come quite a way, but it is definitely not production quality. Xfs-tools is useful if you want to try breaking it - I think I posted on my blog an article about capturing linux kernel core dumps for debugging purposes - it panics quite readily. If you do want to mess with it I'd recommend using the git kernel maintained by the btrfs team. It is obviously bleeding-edge, but due to the high pace of fixes it tends to be more stable than the version in the mainline kernel. Rich
