I have the CentOS 5.5 install DVD and trying to install with software RAID1 on two 2TB SATA drives. The CentOS install only sees one drive. This is a Supermicro motherboard with fakeraid turned off in bios. I tried the trick like so: dd if=/dev/zero of=/dev/sda bs=512 count=64 dd if=/dev/zero of=/dev/sdb bs=512 count=64 Still no go. linux rescue console does see both sda and sdb. Whats going on?
When you boot does the OS see both drives, if so, why not configure using LVM.>>> Matt 12/17/10 6:29 PM >>>I have the CentOS 5.5 install DVD and trying to install with software RAID1 on two 2TB SATA drives.
