NAME
btrfs-inspect-internal - query various internal information
SYNOPSIS
btrfs inspect-internal
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]
(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 ]
(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
set internal buffer for storing the file names to bufsize, default is 4096,
maximum 64k
min-dev-size [options]
(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
specify the device id to query, default is 1 if this option is not used
rootid
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
(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.
