набор инструментов для управления файловыми системами btrfs (a toolbox to manage btrfs filesystems)
Имя (Name)
btrfs - a toolbox to manage btrfs filesystems
Синопсис (Synopsis)
btrfs <command> [<args>]
Описание (Description)
The btrfs utility is a toolbox for managing btrfs filesystems.
There are command groups to work with subvolumes, devices, for
whole filesystem or other specific actions. See section COMMANDS.
There are also standalone tools for some tasks like btrfs-convert
or btrfstune that were separate historically and/or haven't been
merged to the main utility. See section STANDALONE TOOLS for more
details.
For other topics (mount options, etc) please refer to the
separate manual page btrfs(5).
COMMAND SYNTAX
Any command name can be shortened so long as the shortened form
is unambiguous, however, it is recommended to use full command
names in scripts. All command groups have their manual page named
btrfs-<group>.
For example: it is possible to run btrfs sub snaps instead of
btrfs subvolume snapshot. But btrfs file s is not allowed,
because file s may be interpreted both as filesystem show and as
filesystem sync.
If the command name is ambiguous, the list of conflicting options
is printed.
For an overview of a given command use btrfs command --help or
btrfs [command...] --help --full to print all available options.

See btrfs-property(8) for details.
qgroup

See btrfs-qgroup(8) for details.
quota
Manage quota on btrfs filesystem like enabling/rescan and
etc.
See btrfs-quota(8) and btrfs-qgroup(8) for details.
receive
Receive subvolume data from stdin/file for restore and etc.
See btrfs-receive(8) for details.
replace

rescue
Try to rescue damaged btrfs filesystem.
See btrfs-rescue(8) for details.

See btrfs-send(8) for details.
subvolume
Create/delete/list/manage btrfs subvolume.
See btrfs-subvolume(8) for details.
STANDALONE TOOLS
New functionality could be provided using a standalone tool. If
the functionality proves to be useful, then the standalone tool
is declared obsolete and its functionality is copied to the main
tool. Obsolete tools are removed after a long (years)
depreciation period.
Tools that are still in active use without an equivalent in
btrfs:
btrfs-convert
in-place conversion from ext2/3/4 filesystems to btrfs
btrfstune
tweak some filesystem properties on a unmounted filesystem
btrfs-select-super
rescue tool to overwrite primary superblock from a spare copy
btrfs-find-root
rescue helper to find tree roots in a filesystem
Deprecated and obsolete tools:
btrfs-debug-tree
moved to btrfs inspect-internal dump-tree. Removed from
source distribution.
btrfs-show-super
moved to btrfs inspect-internal dump-super, standalone
removed.
btrfs-zero-log
moved to btrfs rescue zero-log, standalone removed.
For space-constrained environments, it's possible to build a
single binary with functionality of several standalone tools.
This is following the concept of busybox where the file name
selects the functionality. This works for symlinks or hardlinks.
The full list can be obtained by btrfs help --box.
Статус выхода (Exit)
btrfs returns a zero exit status if it succeeds. Non zero is
returned in case of failure.
Доступность (Availability)
btrfs is part of btrfs-progs. Please refer to the btrfs wiki
