       btrfs-inspect-internal - query various internal information


       btrfs inspect-internal <subcommand> <args>


       This command group provides an interface to query internal information. The functionality
       ranges from a simple UI to an ioctl or a more complex query that assembles the result from
       several internal structures. The latter usually requires calls to privileged ioctls.


       inode-resolve [-v] <ino> <path>
           (needs root privileges)

           resolve paths to all files with given inode number ino in a given subvolume at path,
           ie. all hardlinks


               verbose mode, print count of returned paths and ioctl() return value

       logical-resolve [-Pv] [-s <bufsize>] <logical> <path>
           (needs root privileges)

           resolve paths to all files at given logical address in the linear filesystem space


               skip the path resolving and print the inodes instead

               verbose mode, print count of returned paths and all ioctl() return values

           -s <bufsize>
               set internal buffer for storing the file names to bufsize, default is 4096,
               maximum 64k

       min-dev-size [options] <path>
           (needs root privileges)

           return the minimum size the device can be shrunk to, without performing any resize
           operation, this may be useful before executing the actual resize operation


           --id <id>
               specify the device id to query, default is 1 if this option is not used

       rootid <path>
           for a given file or directory, return the containing tree root id, for a subvolume
           itself return it’s own tree id (ie. subvol id)

               The result is undefined for the so-called empty subvolumes (identified by inode
               number 2), but such subvolume does not contain any files anyway

       subvolid-resolve <subvolid> <path>
           (needs root privileges)

           resolve the absolute path of a the subvolume id subvolid


       btrfs inspect-internal returns a zero exit status if it succeeds. Non zero is returned in
       case of failure.
