The fact you're using drbd indicates that you're interested in improving the reliablity of your system; while a failover to another system is fairly fast it still represents downtime, breaks active network connections and can cause transactions to be rolled back in a database. Obviosuly, failover sould be avoided if possible, so it makes sense to make the seperate nodes fault tolerant as well by using raid 1/5/6. Now, _IF_ you're using a raid level that provides reliability for your data, you'll want to have some other areas covered as well - even if there's no valuable data stored there but just to allow your system to keep running in case of a disk failure. Two such areas would be: - system swap - drbd metadata Bye, Martin
