Hello. I'm setting up a computer that will run 'CentOS 6 server'. The MB is an Asus with a hw raid controller (Promise PDC-20276), which I want to use in RAID-1 mode. I noted (from a MB website) that it also needs a driver
- which is probably why it's called a 'fakeraid'.
So, I've been trying to determine if any recent kernels support this chip. Using google.com/linux, I found lots of hits dating about 2002 - 04, and referencing the 2.4 kernel (which had the driver compiled into it). But, nothing newer.
I checked kernel.org and kernelnewbies.org - I see that raid-1 is supported. But, I can't find any reference to this chip.
How can I find out what drivers are compiled into a given kernel? Or, basically what hardware a given kernel supports?
Many of the SATA (so-called) hardware raid controllers are not really hardware raid controllers, they are 'fakeraid' and requires lots of software RAID logic. You are generally *better off* to *disable* the motherboard RAID controller and use native Linux software RAID.
