List subvolume quota groups

Shows all quota groups (qgroups) and their space accounting. Each subvolume automatically gets a level-0 qgroup (e.g. 0/256) that tracks its individual usage. Higher-level qgroups (1/0, 2/0, …) can be created to group subvolumes and apply shared limits across them.

Columns:

qgroupid: the quota group identifier in level/id format. Level 0 corresponds to individual subvolumes. Higher levels are user-created grouping containers.

rfer (referenced): total bytes of data referenced by this qgroup. For level-0 qgroups this is the logical size of all extents in the subvolume. Shared extents (e.g. from snapshots or reflinks) are counted in full by each qgroup that references them.

excl (exclusive): bytes used exclusively by this qgroup, not shared with any other qgroup at the same level. This is the space that would be freed if the subvolume were deleted (assuming no other references).

max_rfer: the configured limit on referenced bytes. Writes that would exceed this limit fail with EDQUOT. Shows “none” if no limit is set.

max_excl: the configured limit on exclusive bytes. Shows “none” if no limit is set.

In –format modern, the qgroup hierarchy is shown as a tree: higher- level qgroups appear as parents with their member qgroups nested below using tree connectors.
