Enabling quotas for users

Check to make sure the quota package is installed, else run:

# yum install quota

Edit "/etc/fstab" and add "usrquota,grpquota" to the / partition:

LABEL=/    /    ext3    defaults,usrquota,grpquota    1 1

Then run:

# mount -o remount /
# quotacheck -avugm
# quotaon -avugm

To check quotas for all users:
# repquota -a

To edit quota for a particular user:
# edquota -u <user>

Alternately use setquota:
# setquota <softlimit> <hardlimit> 0 0 <user>
