Hi BTRFS folks, one of my dev boxes is a Thinkpad x220, with a single hybrid (HDD+Flash) disk, running F21 with BTRFS partitions for /home and / . After losing power (ran out of battery, possibly while trying to hibernate) -- the system will not boot. The initrd breaks out to a shell where I find that the partition holding / is failing to mount. - journalctl/dmesg doesn't show anything of interest, though it says there is no hibernate image to restore, and that it cannot mount sysroot - btrfs rescue super-recover says there's no problem, all superblocks ok - btrfs rescue chunk-recover -vy takes a while, and says there's nothing to recover - btrfs check (tried all options) -- says Couldn't open file system - kernel is 3.1.9-200.fc21 - btrfs tools 3.18.1 - disk is a Seagate 500GB Thin SSHD SATA 6Gb/s 64MB Cache 2.5-Inch (ST500LM000) -- cost ~$100 about 2y ago Is there anything I can do here? Anything to recover the partition? Anything to diagnose things in a way that is useful to btrfs development, and understanding of dataloss crashes? A failure of the HDD cannot be ruled out, low power conditions, cheap consumer part... There is no valuable data here, just have to reinstall F21. cheers, martin [ I am not on the list, CC appreciated... ] -- martin.langhoff@xxxxxxxxx - ask interesting questions - don't get distracted with shiny stuff - working code first ~ http://docs.moodle.org/en/User:Martin_Langhoff -- 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
