- _q_u_o_t_a_o_n announces to the system that disk quotas should be enabled on one
- or more local filesystems. The filesystem(s) specified must be mounted at
- the time. _q_u_o_t_a_o_f_f announces to the system that filesystems specified
- should have any disk quotas turned off. Both these commands behave
- slightly differently between EFS and XFS filesystems.
-
- On EFS filesystems, a quota file must be present in the root directory of
- the specified filesystem and be named _q_u_o_t_a_s.
-
- XFS filesystems have two components to their disk quota system:
- accounting and limit enforcement (see _q_u_o_t_a_s(4) ). Except in the case of
- the root filesystem, XFS filesystems require that quota accounting be
- turned on at mount time. It is possible to enable and disable limit
- enforcement on any XFS filesystem after quota accounting is already
- turned on. The default is to turn on/off both accounting and enforcement.
-
- These commands update the status field of devices located in /_e_t_c/_m_t_a_b to
- indicate when quotas are on or off for each filesystem.

- ----aaaa All EFS filesystems in /_e_t_c/_f_s_t_a_b marked read-write with quotas will
- have their quotas turned on. This is normally used at boot time to
- enable quotas. This option does not apply to XFS filesystems.
-
- ----vvvv Display a message for each filesystem where quotas are turned on.
- This is typically useful to find out if the command succeeded or
- not. See also the ----ssss option to _r_e_p_q_u_o_t_a(1M) for monitoring the
- quotaon/off status of a given filesystem.
-
- Quotas on a root XFS filesystem will not take effect until the system is
- rebooted (with the same filesystem as the root filesystem).
-
- OOOOppppttttiiiioooonnnnssss ttttoooo qqqquuuuoooottttaaaaooooffffffff
- ----dddd Remove all the disk space taken up by quota information. This option
- must be used cautiously since it also deletes the limits of all
- users. One possibility is to use it in conjunction with
- _r_e_p_q_u_o_t_a(1M) and _e_d_q_u_o_t_a(1M) as outlined in _q_u_o_t_a_s(4). This command
- applies only to XFS file systems. It is not possible to delete quota
- information while leaving quotas turned on.
