[gentoo-user] software raid, mdadm is not finding disks

[gentoo-user] software raid, mdadm is not finding disks

[Dave]

Hello,
	I'm a new user trying out Gentoo though not a new Linux user. I
wanted to try software raid1. I've got only one machine so this had to go in
to a virtual machine, i installed from the 2008 minimal iso image, the
install went fine, while chrooted /dev/md* devices were working fine, fdisk,
mke2fs, and software installs all worked fine. Upon reboot i'm seeing mdadm
trying to detect the two disks, and not succeeding, therefor unable to mount
/dev/md3 and i'm getting a kernel panic. The disks are /dev/sda and /dev/sdb
two scsi disks on a virtual LSI controller. 
	I then thought boot with the minimal iso again, which i did and
atempt to mount /dev/md3 manually. I'm getting an error that i must specify
the filesystem type and when i do type mdraid is unknown. Any help welcome.
Thanks.
Dave.

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

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

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

RE: [gentoo-user] software raid, mdadm is not finding disks

[Dave]

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

Do you have the lsi fusion kernel driver installed?

RE: [gentoo-user] software raid, mdadm is not finding disks

[Dave]

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