So far all attempts to fix it have failed; hence I am looking for some help (if possible). I was creating a copy of a virtual machine (kvm) on my laptop and started modifying the machine from the inside (installing new packages), when the laptop froze. Rebooting failed because /dev/sda3 (the rootfs) could not be mounted anymore. Some of the errors were btrfs: failed to read log tree btrfs: open_ctree failed Recovery using a Debian/Testing boot stick (kernel 3.10.2, btrfs-tools v0.20-rc1) were unsuccessful so far. After btrfs-zero-log the device was still not mountable. Mount attempts fail with i/o erros now. btrfs restore manages to restore some files from /boot/grub but then fails with failed to inflate: -6 and failed to inflate: -8 and *** Error in `btrfs': free(): invalid next size (normal):0x0000000000c0e650 *** The filesystem is setup as raid1 on devices sda3 and sdb3 using lzo compression. There are subvolumes for /home and /var. Images created with btrfs-image are available from before and after btrfs-zero-log was run. I can make them available if needed. Any hints appreciated!
