        "DESCRIPTION": {
            "content": "fsck.btrfs  is  a  type  of utility that should exist for any filesystem and is called during\nsystem setup when the corresponding /etc/fstab entries contain non-zero value for  fspassno,\nsee fstab(5) for more.\n\nTraditional  filesystems need to run their respective fsck utility in case the filesystem was\nnot unmounted cleanly and the log needs to be replayed before mount. This is not  needed  for\nBTRFS. You should set fspassno to 0.\n\nIf  you  wish  to check the consistency of a BTRFS filesystem or repair a damaged filesystem,\nsee btrfs-check(8). By default filesystem consistency is checked, the repair mode is  enabled\nvia the --repair option (use with care!).\n",
