quotaon(8) System Manager's Manual quotaon(8)
NAME
quotaon, quotaoff - turns quota enforcement on or off
SYNOPSIS
/usr/sbin/quotaon [-guv] file_spec ...
/usr/sbin/quotaon -a [-guv]
/usr/sbin/quotaoff [-guv] file_spec ...
/usr/sbin/quotaoff -a [-guv]
PARAMETERS
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: /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 exam-
ple: root_domain#root.
FLAGS
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.
DESCRIPTION
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 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 flag to specify only group quotas or
the -u flag 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
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 file system.
RESTRICTIONS
You must be the root user to run the quotaon and quotaoff commands.
