See, these other SNs, are also pulling double duty as servers of various kinds; DNS, web, install server (FAI), etc. But those services obviously do not need nearly as much disk space on them as they happen to have. Which is what led me to the idea of just using one system as an Access Node to export NFS/CIFS, and manage the remainder of the disk space via LVM. I was planning on mirroring across SNs using Linux's SW RAID, and I had considered doing a 4-way mirror of the boot partition on each node as well, but I wanted to conquor the NBD-SN-AN idea first :) -- Seeya, Paul -- It may look like I'm just sitting here doing nothing, but I'm really actively waiting for all my problems to go away.
