I'm definitely going to revisit migrating to SSD's once I get it all up and running! On a different note: I was thinking of doing the disk setup like this: <sda1><sdb1> | <md1> | <ext3> <!-- System Partition <sda2><sdb2> | <md2> | <drbd> | <pv1> | <vg1> | <lv(s)> | <ext3> <!-- Application Partition and <sda3><sdb3> | <md3> | <drbd> | <pv2> | <vg2> | <lv(s)> | <ext3> <!-- Postgresql Partition Putting in the lvm mainly to do snapshot style backups. This makes me wonder if it's a doable usecase to add more drives and have more than one drbd partition in a pv group and then resize the lv if needed to increase space (Man that's wild stuff). But anyway, is setting up a pv on top of a drbd a good idea? J
