BTRFS-QGROUP(8)                  Btrfs Manual                  BTRFS-QGROUP(8)

       btrfs-qgroup - control the quota group of a btrfs filesystem

       btrfs qgroup <subcommand> <args>

       btrfs qgroup is used to control quota group(qgroup) of a btrfs

           To use qgroup, it needs to enable quota first using btrfs quota

           Qgroup is not stable yet and will impact performance in current
           mainline kernel(v3.14 so far).

       Quota group or qgroup in btrfs has its hierarchy like subvolume. One
       subvolume/snapshot can reach its quota limits if it consumes all the
       quota assigned to it or any of the parent qgroup(s).

       Also for snapshot, it consumes no quota initially since all its data
       shares with its parent, so only modification in snapshot consumes

       Every subvolume/snapshot will have its own qgroup with id 0/<subvolume
       id>'' upon creating, but can be later destroyed by btrfs qgroup destroy

           If the qgroup of a subvolume is destroyed, quota about the
           subvolume will not be functional until qgroup 0/<subvolume id>'' is
           created again.

       assign <src> <dst> <path>
           Assign qgroup <src> as the child qgroup of <dst> in the btrfs
           filesystem identified by <path>.

       remove <src> <dst> <path>
           Remove the relationship between child qgroup <src> and parent
           qgroup <dst> in the btrfs filesystem identified by <path>.

       create <qgroupid> <path>
           Create a subvolume quota group.

           For the 0/<subvolume id>'' qgroup, a qgroup can be created even
           before the subvolume created.

       destroy <qgroupid> <path>
           Destroy a qgroup.

           If a qgroup is no isolated,which means it is a parent or child
           qgroup, it can't be destroyed.

       show [options] <path>
           Show all qgroups in the btrfs filesystem identified by <path>.


               print parent qgroup id.

               print child qgroup id.

               print max referenced size of qgroup.

               print max exclusive size of qgroup.

               list all qgroups which impact the given path(include ancestral

               list all qgroups which impact the given path(exclude ancestral

               list qgroups in order of <attr>.

               <attr> can be one or more of

               Prefix '+' means ascending order and '-' means descending order
               of <attr>. If no prefix is given, use ascending order by

               If multiple '<attr>'s is given, use comma to separate.

       limit [options] <size>|none [<qgroupid>] <path>
           Limit the size of a qgroup to <size> or no limit in the btrfs
           filesystem identified by <path>.

           If <qgroupid> is not given, qgroup of the subvolume identified by
           <path> is used if possible.

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

       btrfs is part of btrfs-progs. Please refer to the btrfs wiki for further details.
