SYNOPSIS
/usr/sbin/quotaon [-guv] file_spec...
/usr/sbin/quotaon -a [-guv]
/usr/sbin/quotaoff [-guv] file_spec...
/usr/sbin/quotaoff -a [-guv]
OPTIONS
Turns on (with quotaon) or turns off (with quotaoff) quotas for all
file systems identified in the /etc/fstab file as read/write with quo‐
tas. 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.
OPERANDS
Specifies one or more file systems. Specify any file system by enter‐
ing 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: /dev/disk/dsk3c.
For AdvFS filesets, you can alternatively enter the name of a
file domain, a pound sign (#), and the name of the fileset. For
example: root_domain#root.
DESCRIPTION
The quotaon and quotaoff commands enable or disable user and group quo‐
tas 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 authority.
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 user quotas.
NOTES
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 quotas.
AdvFS always maintains user and group file and block usage in the quota
files (quota.user and quota.group). User and group quota limit infor‐
mation 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 file system.
RESTRICTIONS
You must be the root user to run the quotaon and quotaoff commands.
