Eduardo: To give you something else to consider, as an alternative: I believe there was a long thread here, awhile back, about using Software RAID, instead of fake RAID controllers. Software RAID works very well, as I recall from reading that thread. Possibly look into changing to Software RAID. Depends on the HW RAID controller.
Yes, I finally ended up installing software RAID because 1) I have read that, even if I installed the proper driver, Linux only uses it to configure its own dm software RAID device according to the BIOS conf-- is this completely true? If yes, no real offloading anything to hardware anyway-- even under Windows; does anybody know about this for sure? 2) I am very scared by non-kernel-tree-blessed modules which have their own install procedures and/or updating schedule, I have been bitten by this in the past.
I finally did setup two 1-RAIDed identical partitions and installed the system on the rest of both disks... Now my system won't boot if one disk is broken, but I hope I can go rescue into the data. I was formerly hoping to rely on RAID to protect the full install and simplify my life, but I was discouraged away by 1) and 2).
I have yet to see a real RAID controller... At what price do they start off?
