 Posted: Tue Jul 20, 2004 4:43 am Post subject: Adding users & XFS disk quotas |
 |
|
Hi,
1) Well firstly I'd like to know if it is possible to activate multiple users for diskquotas with edquota command, lets say all people in /etc/passwd with UID > 1000. Any other ways? I only need to add non-root users (about 40 of them). I also have machine names in /etc/passwd and theres no need to enable quotas for them. Another idea, how to enable every user that has home dir in /home/users ?
2) How do disable disk quotas for some users after enabling them?
3) quotacheck -avug always spits out:
| Code: |
quotacheck: Skipping /dev/md2 [/home/users]
quotacheck: Can't find filesystem to check or filesystem not mounted with quota option.
|
and quotacheck -avug -F xfs gives
| Code: |
root@a216server instructor # quotacheck -avug -F xfs
XFS quota format needs no checking.
|
How to go around that?

In order to activate quota on xfs (or on any fs for that matter) you must mount the partition with quota/usrquota/grpquota option.
XFS do not need quotacheck so don't use it.
All users have by default unlimited access (no quota).
For giving back unlimited access to a user you should set quotas to 0:
| Code: | | setquota -u $luser 0 0 0 0 |
The easy way to set a quota is to write your own script that refreshes quotas for users:
| Code: | #!/bin/sh
function set_quota() {
setquota -u $1 $2 $[ $2 * 11 / 10] $3 $[ $3 * 11 / 10 ] -a
}
# users (gid = 100)
awk -F: '$3 >= 500 && ( $4 == 100 || $4 == 1000 ) { print $1; }' /etc/passwd | \
(
while read LUSER; do
case $LUSER in
*.support)
BLOCK=$[3000 * 1024]
INODE=0
;;
*)
BLOCK=$[1000 * 1024]
INODE=20000
;;
esac
set_quota $LUSER $BLOCK $INODE
done
)
set_quota ftp $[2000 * 1024] 10000
repquota -a
|
You should run this script whenever you add a new user and want to limit its disk quota. |

I really don't get it with quotas. How do I set a quota of 50 Mb (hard) with your script ? No soft quota and no file limit. ?
EDIT: I also had another question.. If i set a quota for the group "hebb" of 50 mb, will it set max 50 mb. by user in this group, or a single quota for all these users ?
Thanks, Phil

if i got it right, you set quotas with the setquota-command. for the group hebb:
| Code: |
setquota -g hebb 49000 50000 0 0
|
this means, that the group, the whole group includes all users in this group, has a block limit (soft) of 49 mb (it's a bit less in fact, because i didn't multiplicate with 1024) and a hard limit of 50 mb.
if you want quotas for users, you have to use the "-u" switch with setquota. the latter two numbers means a file limit. you can see how much auf a quota is used with the repquota-command.
