Struct QuotaStatusCommand 

pub struct QuotaStatusCommand {
    pub path: PathBuf,
    pub is_enabled: bool,
}

Show status information about quota on the filesystem

Displays the current quota configuration and accounting state. The fields shown when quotas are enabled:

Enabled: whether quota accounting is active on this filesystem.

Mode: the accounting mode. “qgroup” (full accounting) tracks every extent backref and provides accurate shared/exclusive byte counts. “squota” (simple quotas, kernel 6.7+) uses lighter-weight lifetime tracking that avoids the overhead of full backref walking but does not distinguish shared vs exclusive usage.

Inconsistent: if “yes”, the qgroup numbers are stale and a rescan is needed (btrfs quota rescan). This happens after unclean shutdowns or when qgroups are first enabled on an existing filesystem.

Override limits: when enabled, qgroup limits are not enforced for the current mount. Writes will succeed even if they exceed the configured limits. Useful for emergency recovery.

Drop subtree threshold: controls how deep the kernel tracks qgroup changes when deleting subvolumes. Levels below this threshold skip detailed per-extent accounting during heavy delete workloads, trading accuracy for performance. A value of 0 means full tracking.

Total count: the total number of qgroup entries in the quota tree.

Level 0: the number of level-0 qgroups. Each subvolume automatically gets a level-0 qgroup (e.g. 0/256, 0/257). Higher-level qgroups (1/0, 2/0, …) are user-created containers for hierarchical limits.

Fields

path: PathBuf

Path to a mounted btrfs filesystem

is_enabled: bool

Only check if quotas are enabled, without printing full status
