btrfs root filesystem corruption
- Linux hangs, i rebooted with with power button.
- Only boots into rescue shell can't mount btrfs root raid0 over two ssd's.
- Boot with live Ubuntu 16.04 usb thumbdrive.
$ sudo btrfs rescue chunk-recover -y -v /dev/sda2 > btrfs_rescue_chunk-recover-y-v.txt
- capture btrfs rescue, with stdio+stderr to one file and stderr to 2nd file
$ sudo btrfs rescue chunk-recover -y -v /dev/sda2 2>btrfs4.9.1_error.out.txt 1>btrfs4.9.1_stdio.out.txt
