If supplied in place of any file system names, / quotaoff will enable/disable all the file systems indicated in /etc/fstab to be read-write with disk quotas. By default only the types of quotas listed in /etc/fstab are enabled.
Only group quotas listed in /etc/fstab should be enabled/disabled.
Only user quotas listed in /etc/fstab should be enabled/disabled.
Cause quotaon and quotaoff to print a message for each file system where quotas are turned on or off.
Specifying both -g and -u is equivalent to the default.
