So you're getting dropped to a dracut prompt? i.e. you're in the initramfs and root fs is not mounted at /sysroot, so if you ls /sysroot there's nothing there, right? If so you can try: mount -o recovery /dev/ /sysroot If you get no major errors then mount to see if it's mounted at /sysroot and if so exit will resume boot. If the -o recovery mount fails, then it's a bit trickier. It's probably easiest to take a cell phone photo of the error message if it's not super short to copy out. And then btrfs check <dev> Again cell phone is easier, it's a lot to write out. But the problems are important as is the btrfs-progs baked into the initramfs. Someone might know if that version of btrfs-progs is safe to try a repair given the problem output from check. If no one replies soon enough for you, I probably wouldn't use --repair unless I had v.3.18, in which case you probably need live media and update its btrfs-progs after booting from it. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
