[Btrfs-devel] reversing the effects of mkfs.btrfs?

[Peter Teoh]

I was playing  around with btrfs, and did a  mkfs.btrfs on one of my
partition.   Mistakes, it was my data partition (ext3 based).

I have not yet mounted the device, but the mkfs.btrfs continued to
completion.

Is it possible to salvage my ext3 filesystem?   Anyway to reverse the
effect of mkfs.btrfs?

Thank you for your help/answer.
