Quotas - installation and configuration
James wrote in with this how-to. ═ Thank you.
Add QUOTA to your kernel
Your kernel needs the following in its kernel configuration file:
options QUOTA
For instructions on how to create a new kernel, refer to the
Configuring the FreeBSD Kernel section in the FreeBSD handbook.
Pay special attention to the section on Building and
Installing a Custom Kernel.
Specify the partitions
Decide what partitions you want to enable quota checking on and modify
/etc/fstab accordingly.═ For each partition for which you want quotas
enabled, modify that line in the file.═ userquota is for individual
user quotas whereas.═ groupquota is for entire group quotas (i.e. the
restrictions apply to groups as a whole).
For example:
/dev/ad0s1f /home ufs rw,userquota,groupquota 2 2
quotacheck
Start out by typing:
quotacheck -a
This will create all the needed database files for the next command to
work
quotaon/quotaoff
The following command will enable quotas for all quota-flagged
partitions listed in /etc/fstab:
quotaon -a
You can also issue this command to enable quotas only for the
partition /mount_point (replace /mount_point with the partition
applicable to your needs):
quotaon /mount_point
quotaoff has the same syntax as quotaon, but as the name implies, it's
used to turn off quota.
user quotas
To edit user quotas, issue the following command:
edquota -u username
This excerpt from the edquota man page should help with editing
quotas:
Users are permitted to exceed their soft limits for a grace period
that may be specified per filesystem. Once the grace period has
expired, the soft limit is enforced as a hard limit. The default
grace period for a filesystem is specified in
/usr/include/ufs/ufs/quota.h. The -t flag can be used to change the
grace period.
After you're done editing the quota file, save your changes and exit
the editor.
Repeat this step for each user that you want to have a quota.═ If you
have a bunch of users that will use the same quota settings, type
something like the following:
edquota -u -p user1 user2 user3 user4
This will copy the quota settings from user1 to user2, user3, and
user4. Specify as many users as you need to copy the quotas.
group quotas
You can edit the quotas for a group by typing:
edquota -g groupname
Starting quotas at boot time
To ensure quotas are enforced after a reboot, add the following line
to /etc/rc.conf:
quota_enable="YES"
check_quotas="YES"
Checking the usage
There will come a time that you will want to check your quota usage.
Simply type the following command to check your quota:
quota
Or, if you're root, you can check quotas of other users by typing:
quota username
