So, I was trying to downgrade my Ubuntu last night, and, before doing anything risky like that, I backed up my disk via dd to an image on an external disk. The critical part here is that I'm afraid I did something truly stupid: I'm afraid I did the dd... live. (I can't swear to this, and it does seem unlikely, but it also seems to be the most likely circumstance.)
So, I dd'd everything back, and now it crashes on boot. Booting to a 2.6.x kernel (which is what I had on-hand on a USB drive) mounts it, but doesn't let me *do* anything (though it spews btrfs errors in dmesg). Getting Ubuntu 11.10 (kernel rev. 3.0.0) gives me this: [ 121.226246] device fsid d657ce6a-d353-4c2c-858a-6a1f4d9e766e devid 1 transid 217713 /dev/sda1 [ 121.232430] parent transid verify failed on 100695031808 wanted 217713 found 217732 [ 121.232898] parent transid verify failed on 100695031808 wanted 217713 found 217732 [ 121.233357] parent transid verify failed on 100695031808 wanted 217713 found 217732 [ 121.233365] parent transid verify failed on 100695031808 wanted 217713 found 217732 [ 121.248231] btrfs: open_ctree failed As I have this complete image on-disk, I'm more than willing to try Extreme Measures(tm), whatever that might entail. If I can't get it back, it's not like it's the loss of my job or anything, but there *is* stuff I'd really like to get back.
