Turns on (with quotaon) or turns off (with quotaoff) quotas
for all file systems identified in the /etc/fstab file
as read/write with quotas. Turns on or off group quotas
only. Turns on or off user quotas only. Prints a message
for each file system whose quotas are turned on or off.
Specifies one or more file systems. Specify any file system
by entering its full path name or its mount point. The
full path name is the name entered in the file-spec field
of the file system's entry in the /etc/fstab file. The
mount point is the name entered in the mnt_point field of
the file system's entry in the /etc/fstab file.
For UFS file systems, you can alternatively enter
the name of a block device special file. For example:
For AdvFS filesets, you can alternatively enter the
name of a file domain, a pound sign (#), and the
name of the fileset. For example:
The quotaon and quotaoff commands enable or disable user
and group quotas that have been established using the
edquota command. To turn the quotas on or off, the file
systems specified must have the userquota and groupquota
entries in the /etc/fstab file and be mounted at the time.
quotaon and quotaoff must be run by a user with superuser
These commands expect each file system to have quota files
named quota.user and quota.group in the root directory of
the file system. (These default file locations may be
overridden in the /etc/fstab file.)
By default, both user and group quotas are affected by
the quotaon and quotaoff commands. Use the -g option to
specify only group quotas or the -u option to specify only
The term file system represents either a UFS file system
or an AdvFS fileset.
The quotaon and quotaoff commands are used to manage user
and group quotas: they are not used to manage AdvFS fileset
quotas. Use the chfsets command to set or clear fileset
AdvFS always maintains user and group file and block usage
in the quota files (quota.user and quota.group). User and
group quota limit information displays with the showfsets
command even if quota enforcement is turned off.
When a file system is unmounted, user and group quotas are
disabled. After a file system has been remounted, use the
quotaon command to enable user and group quotas on the
You must be the root user to run the quotaon and quotaoff
