NAME btrfs - control a btrfs filesystem
SYNOPSIS btrfs <command> [<args>]
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.
COMMAND SYTNAX Any command name can be shortened as far as it stays 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.
COMMANDS balance Balance btrfs filesystem chunks across single or several devices. See btrfs-balance(8) for details. check Do off-line check on a btrfs filesystem. See btrfs-check(8) for details. device Manage devices managed by btrfs, including add/delete/scan and so on. See btrfs-device(8) for details. filesystem Manage a btrfs filesystem, including label setting/sync and so on. See btrfs-filesystem(8) for details. inspect-internal Debug tools for developers/hackers. See btrfs-inspect-internal(8) for details. property Get/set a property from/to a btrfs object. See btrfs-property(8) for details. qgroup Manage quota group(qgroup) for btrfs filesystem. 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 Replace btrfs devices. See btrfs-replace(8) for details. rescue Try to rescue damaged btrfs filesystem. See btrfs-rescue(8) for details. restore Try to restore files from a damaged btrfs filesystem. See btrfs-restore(8) for details. scrub Scrub a btrfs filesystem. See btrfs-scrub(8) for details. send Send subvolume data to stdout/file for backup and etc. See btrfs-send(8) for details. subvolume Create/delete/list/manage btrfs subvolume. See btrfs-subvolume(8) for details.
