1 Hello,
2 I had the LSI driver loading as a module. I recompiled the kernel
3 and made it monolithic, put in the raid and other drivers in that way and
4 rebooted. It is working!
5 That also explains another unrelated issue.
6 Thanks a lot.
7 Dave.

16 Do you have the lsi fusion kernel driver installed?

25 Hello,
26 Thanks for your reply. I did change the type of the
27 partitions on
28 both disks to fd linux raid autodetect. When i rebooted in to the
29 live CD i
30 gave it the mdadm -A /dev/md3 /dev/sda3 /dev/sdb3 it found both
31 drives and
32 brought them up. I was then able to mount the array.
33 In my kernel config file i do have CONFIG_MD_RAID1 set to Y.
34 I've just tried compiling a genkernel and got the same error when i
35 tried to
36 load it. Any suggestions welcome.
37 Thanks.
38 Dave.

47 A couple of things when you reboot into the live cd you need to tell
48 mdadm
49 to assemble the drive /dev/md3 with the command mdadm -A /dev/md3
50 /dev/sda3
51 /dev/sdb3. As for the booting problem i think it may be that you are
52 missing
53 a driver did you put the md raid 1 driver into the kernel. Last Neil
54 has a
55 point when you ran fdisk did you change the partition type to auto
56 detect
57 raid.

73 Did you set the partition type to Linux RAID Autodetect (FD)?

79 If at first you do succeed, try to hide your astonishment.
