NAME

       btrfs-inspect-internal - query various internal information

SYNOPSIS

       btrfs inspect-internal <subcommand> <args>

DESCRIPTION

       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.

SUBCOMMAND

       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

           Options

           -v
               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

           Options

           -P
               skip the path resolving and print the inodes instead

           -v
               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

           Options

           --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)

               Note
               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

EXIT STATUS

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