Jimmy: I notice the Opteron box has 3 SCSI drives attached. sda is the system drive, then there are sdb and sdc... all are 30 GB, but only sda seems to be partitioned. Is this as it should be, or was there supposed to be a RAID setup? I don't remember...
Those should be 36GB each.
This should be a RAID 5 array, 2+1, for a total logical volume of whatever, 72Gb-ish I guess?
Upon closer inspection, though, it looks like I've made a slight mistake.
LSI 20320 1 Channel U320 SCSI Controller is what I ordered.

This card only supports RAID 0 or RAID 1.
For our immediate purposes, which do we want? Mirroring (safety) or striping (performance)?
I'm thinking, but correct me if I'm wrong, that we can have one of the other machines run a replicator, giving us safety, and then we can do striping on this machine for performance.
In the future, when geoffrin is healthy and is the primary, Jimbo the President of the Wikimedia Foundation, Inc. will call Jimbo the President of Bomis, Inc., and complain. Jimbo@Bomis is responsible for the error, so we'll make him pay for a new card!

p.s. In any event, is it reasonble to suppose that I need to do something hardware wise to setup striping?
