lvm user quota

Whats the best method of setting lvm user quota? I saw both of these and I am not sure which to use.

Linux File System Quotas
Howtos Linux-Vserver With LVM And Quotas - 5dollarwhitebox.org Media Wiki

The second link is for a Debian VServer. Personally I've never used that but the "traditional" way of setting up quotas on RHEL-based systems is by adding "usrquota" or "grpquota" to /etc/fstab and using commands like "quotaon", "edquota", "setquota", etc.
