Liivo, pvdata shows that you had _two_ physical volumes in your volume group before and that "vg" is exported? Why is it exported when your other drive crashed and where's the other physical volume belonging to "vg"? Was it eventually on the dead drive? In that case it is pretty unlikely that you can retrieve a lot of your logical volume date anyways. Even if you replace that drive, you won't get that data back which went down the drain woth it. If you don't find the other physical volume with "pvscan -u" (look for UUID Zy48rM-UOIi-0gP7-TvjK-apfK-4oJ1-0rvV2b) and if my assumptions are correct you want to go for a restore. Hopefully you've got a recent backup.
