I've spent a good part of my career working on such systems so I know
exactly what you're talking about -- but I'm a software developer -- not
the sysadmin that sets up the RAID stuff -- so the details here are new
to me ;-) As I said before, my requirements aren't for a high
availability server -- just trying to reduce the window of possible data
loss a little more. If one of the 2 drives ever fail I could surely
continue with no problem for a long time before replacing it.
Thx,
