NAME
       btrfs-select-super - overwrite superblock with a backup


SYNOPSIS
       btrfs-select-super -s number dev


DESCRIPTION
       btrfs-select-super destructively overwrites all copies of the superblock with a specified copy. This
       helps with certain cases of damage, especially when barriers were disabled during a power failure. You
       can find a valid copy of the superblock with btrfs check -s.

       The filesystem specified by dev must not be mounted.


OPTIONS
       -s|--super <superblock>
           use <superblock>th superblock copy, valid values are 0 up to 2 if the respective superblock offset is
           within the filesystem
