NAME
       btrfs-rescue - Recover a damaged btrfs filesystem

SYNOPSIS
       btrfs rescue <subcommand> <args>

DESCRIPTION
       btrfs rescue is used to try to recover a damaged btrfs filesystem.

SUBCOMMAND
       chunk-recover [options] <device>
           Recover the chunk tree by scanning the devices

           Options

           -y
               assume an answer of yes to all questions.

           -v
               verbose mode.

           -h
               help.

           Note
           Since chunk-recover will scan the whole device, it will be VERY slow especially
           executed on a large device.

       super-recover [options] <device>
           Recover bad superblocks from good copies.

           Options

           -v
               verbose mode.
