I have a single hard drive that the OS is installed on and I have Sil raid card installed with two matching 500GB hdds set up in Raid 0 and formatted- they're completely empty. For whatever reason they are showing up as /dev/sdb and /dev/sdc and not as a single hard drive. I used fdisk
to format both raid drives as Linux raid auto (fd
) but I cannot mount either device and dmraid doesn't seem to want to work, what step am I missing?
When I installed 9.04 oh so long ago it seems like it recognized and automatically did everything that needed to be done, now I'm stuck.
