Hi, I have a server with the below SATA RAID controller and i have configured RAID 1 mirror in the BIOS using 2 SATA drives. Fedora core 4 install went smoothly [ Funny thing was that I had to type in 'linux anything' at the installer boot prompt first and then type linux to get the installer going. Read this workaround in some forum ] 00:1f.2 RAID bus controller: Intel Corporation 6300ESB SATA RAID Controller (rev 02) (prog-if 8f) Subsystem: Intel Corporation: Unknown device 3451 Flags: bus master, 66Mhz, medium devsel, latency 0, IRQ 177 I/O ports at cf80 [size=8] I/O ports at cf00 [size=4] I/O ports at ce80 [size=8] I/O ports at ce00 [size=4] I/O ports at cd80 [size=16] This RAID controller is supposed to be ICH5 chipset and supported by dmraid but dmraid doesnt show me any software RAID sets.

Below are the versions [root@localhost ~]# dmsetup version Library version: 1.01.04 (2005-08-02) Driver version: 4.4.0 [root@localhost ~]# dmraid -V dmraid version: 1.0.0.rc8 (2005.05.19) debug dmraid library version: 1.0.0.rc8 (2005.05.19) device-mapper version: 4.4.0 How can i get RAID 1 configured on this (fakeraid) RAID controller ? Does dmraid support it ? Please advice. TIA Dushyanth
