when the sun tech installed the hard drive array he made one big 4TB partition. when i finally made my mind up about which size quota to give each user i realized that i needed to have a separate partition for the quotas. i used lvm to resize the partition and created an additional partition for the mail server to use. in /etc/fstab there needed to be an option to enable usrquota. after any changes are made to fstab the partitions need to be remounted. once this is done the quota files need to be generated. use the command “time /sbin/quotacheck -vguma” after the quota files have been set up, the quotas need to be set for all users
