1. Take a backup of /etc/fstab file first and then put following entry in /etc/fstab
LABEL=/local/1 /local/1 ext3 defaults,usrquota,grpquota 1 2
P.S. If there is already an entry like below, replace it with the above line
/dev/sdb1 /local/1 ext3 defaults 1 2
2. Issue following command
#mount -o remount /local/1/
# quotacheck -vc /local/1/
Check using following command if userquota and grpquota attributes are applied to /local/1
root@tksddvm003lx01jee:/local/1/home# mount|grep /local/1
/dev/sdb1 on /local/1 type ext3 (rw,usrquota,grpquota)
3. Issue following commands one by one.
#/sbin/quotaoff -vug /local/1
#
# ls -ltr /local/1/aquota.*
-rw------- 1 root root 35840 Nov 18 18:44 /local/1/aquota.user
-rw------- 1 root root 19456 Nov 18 18:44 /local/1/aquota.group
#/sbin/quotaon -vug /local/1
/dev/sdb1 [/local/1]: group quotas turned on
/dev/sdb1 [/local/1]: user quotas turned on
# /sbin/quotaon -p /local/1
group quota on /local/1 (/dev/sdb1) is on
user quota on /local/1 (/dev/sdb1) is on
# /usr/sbin/warnquota
root@tksddvm003lx01jee:/local/1/home
An over-limit quota generates a mail message to the user on login. Which file would you modify to customize the mail delivered ?
A: /etc/warnquota.conf
4. Quota is set. You can list is using following command
# /usr/sbin/repquota –a
5. Now set quota limits to one of the service id (we are using tketrwfd as an example)
# /usr/sbin/edquota -u tketrwfd
Disk quotas for user tketrwfd (uid 1208137):
Filesystem blocks soft hard inodes soft hard
/dev/sdb1 312088 1020000 1500000 6187 0 0
Confirmation:
# /usr/sbin/repquota -a|grep tketrwfd
tketrwfd -- 312088 1020000 1500000 6187 0 0
P.S. We implement quota limits on the blocks and not on inodes. So entries needs to be made under belonging to Blocks columns.
6. Now use above service id’s (tketrwfd) quota limits as template and create quota limits for all jfarm service id’s using following command.
# cd /local/1/home;for i in `ls -1`;do /usr/sbin/edquota -p tketrwfd $i;done
Confirmation:
#/usr/sbin/repquota -a
*** Report for user quotas on device /dev/sdb1
