That depends on the version of the kernel in use. I remember having
lost all data of a
btrfs file system with an early 3.x kernel. Meanwhile there have been
quite a lot of patches
to btrfs. With the more recent kernels (>= 3.6 I believe) this hasn't
happened any more.
I'd recommend kernel 3.8.x, at least (I'm running 3.9_rc7)
I remember that only last week,
/sbin/btrfsck --repair <DEVICE> failed with some spurious error on a
btrfs file system which happily turned out to be just OK. Note, that I
emerge the GIT sources
of btrfs-progs whenever I install a new kernel (each week in the last 7
weeks).
So, as of now, I wouldn't rely on btrfsck doing a good job.
But my btrfs file systems survived quite a few power losses without the
need to
btrfsck them.
