While running the stable branch of 64-bit Debian, rebooted into an alternative OS, but forgot to unmount a USB device beforhand. Shutdown was taking too long, so forced it anyway. Now when I try to start Linux, I get these error messages:
[1.922640] platform gpio_ich.2.auto: failed to claim resource 0:[io 0x0480-0x04ff] [8.934607] BTRFS error (device sdc2): parent transid verify faild on 176160768 wanted 680981 found 680979 [8.934649] BTRFS error (device sdc2): failed to read block groups 1 - 5 [8.935724] BTRFS error (device sdc2): open_ctree failed mount: mounting /dev/sdc2 on /root failed: invalid argument failed to mount /dev/sdc2 as root file system Then the initramfs command prompt appears. A little hard to find much on that. Read in the btrfs wiki that <-o ro,usebackuproot> with the mount command could help when the "wanted" and "found" numbers were not too far apart. mount -t btrfs -o ro,usebackuproot /dev/sdc2 TRIED with: /sysroot GOT: mount: mounting /dev/sdc2 on /sysroot failed: invalid argument TRIED with: / GOT: mount: mounting /dev/sdc2 on / failed: invalid argument TRIED with: /root GOT: mount: mounting /dev/sdc2 on /root failed: invalid argument Is this a GRUB issue, a btrfs issue, or must I reinstall the operating system, and if so where can I find out which files must be preserved in order to maintain continuity?
