btrfs-quota - control the quota of a btrfs filesystem
btrfs quota <subcommand> <args>
btrfs quota is used to enable/disable or rescan subvolume quota of a btrfs filesystem. For setting quota or other quota operations on a btrfs filesystem, please see btrfs-qgroup(8) for details. Warning Quota and qgroup in btrfs filesystem is not stable and impacts performance in mainline kernel yet(v3.14 so far).
disable <path> Disable subvolume quota support for a filesystem. enable <path> Enable subvolume quota support for a filesystem. rescan [-s] <path> Trash all qgroup numbers and scan the metadata again with the current config. Options -s show status of a running rescan operation. -w wait for rescan operation to finish(can be already in progress).
btrfs quota 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 http://btrfs.wiki.kernel.org for further details.
