Hi Brian, and thank you for your comments - my apologies for being so =
long replying, I seem to have set up the mailing list wrong so that I=92m =
not receiving responses. Not sure how to fix it, so I guess I=92ll just =
need to check the archives regularly.
We bought the soft controller for cost reasons: we=92re a small =
university lab, and we just couln=92t afford hardware RAID controllers =
at the time. That argument applies all the more strongly now, as for =
various reasons the system only needs to survive another year or so. So =
unfortunately we=92re stuck with a software controller. I could just =
skip upgrading the system for that time, but we=92re receiving a huge =
number of attempted break-ins every day, so I prefer not to take =
security risks.
Thank you for the ubuntu link. I=92ve gone through it carefully, but I =
coulnd=92t find anything useful there (I don=92t want to use dkms =
directly, because failures under dims would be even harder to fix - at =
least if there is a failure building the module manually, I get to see =
it at the time, which means I can reset the kernel default to the =
preceding kernel, reboot, remove the latest kernel and rebuild again - =
and I can do this remotely (the system is in a lab a fair way form my =
home/work). Relying on DKMS in this circumstance, where builds fail on a =
regular basis, sounds a bit too dangerous.
Thanks and Best Wishes

Bob,
Some questions & recommendations:
Why not use a supported RAID controller for a production server?
Have you tried using DKMS? I found a guide for Ubuntu and a lot of what =
it says applies to Fedora:
https://help.ubuntu.com/community/RocketRaid
If I were the sysadmin of your box and it needed to be online as much as =
possible, I would use a LSI RAID controller. There are others out there =
which work, but I=92m most familiar with LSI. Many vendors integrate =
their RAID controllers into their own RAID cards (Dell PERC, for =
example). I would most definitely stay away from RAID controllers where =
the driver is not integrated into the mainstream kernel.
Just my 2 cents.
