QUOTAON(8) BSD System Manager's Manual QUOTAON(8)NAME
quotaon, quotaoff — turn filesystem quotas on and off
SYNOPSISquotaon [-g] [-u] [-v] filesystem ...
quotaon [-g] [-u] [-v] -a
quotaoff [-g] [-u] [-v] filesystem ...
quotaoff [-g] [-u] [-v] -a
Quotaon announces to the system that disk quotas should be enabled on one
or more filesystems. Quotaoff announces to the system that the specified
filesystems should have disk quotas turned off. The filesystem must be
mounted and it must have the appropriate mount option file located at its
root, the .quota.ops.user file for user quota configuration, and the
.quota.ops.group file for group quota configuration. Quotaon also
expects each filesystem to have the appropriate quota data files located
at its root, the .quota.user file for user data, and the .quota.group
file for group data. These filenames and their root location cannot be
overridden. By default, quotaon will attempt to enable both user and
group quotas. By default, quotaoff will disable both user and group quo‐
-a If the -a flag is supplied in place of any filesystem names,
quotaon/quotaoff will enable/disable any filesystems with an
existing mount option file at its root. The mount option file
specifies the types of quotas that are to be configured.
-g Only group quotas will be enabled/disabled. The mount option
file, .quota.ops.group, must exist at the root of the filesystem.
-u Only user quotas will be enabled/disabled. The mount option
file, .quota.ops.user, must exist at the root of the filesystem.
-v Causes quotaon and quotaoff to print a message for each filesys‐
tem where quotas are turned on or off.
Specifying both -g and -u is equivalent to the default.
Quotas for both users and groups will automatically be turned on at
filesystem mount if the appropriate mount option file and binary data
file is in place at its root.
Each of the following quota files is located at the root of the mounted
filesystem. The mount option files are empty files whose existence indi‐
cates that quotas are to be enabled for that filesystem.
.quota.user data file containing user quotas
.quota.group data file containing group quotas
.quota.ops.user mount option file used to enable user quotas
.quota.ops.group mount option file used to enable group quotas
