Hi folks:
We have been trying to build an operational initrd for a root drive
on software RAID1.
Basic specs: 2.6.23.14 kernel (though same issues with 2.6.27.2
kernel), on Centos 5.2, pair of SATA drives using libata and other
drivers, x86_64 architecture.
Using mkinitrd --with=raid1 --with=libata --with=sd_mod ...
I am getting a kernel panic on switchroot, it can't find the root
file system.
Hi Joe,
What does the "root=" kernel parameter look like in your grub.conf (are
you using grub?)? Mine looks like root=/dev/md2. My md0 is the boot
partition and md1 is swap. I know this is simplistic but I didn't find
it in your message.

I did some googling, but could not find a similar
example. Do I need to create a specialized init script? Is there an
example of this somewhere? I did look at the Documentation/md.txt and
tried the
md=0,sda1,sdb1 md=1,sda2,sdb2 md=2,sda3,sdb3
kernel boot time option, to no avail. Persistent superblocks are
on, and the devices have the right partition types.
Any suggestions? More things to read?
Thanks in advance.
Joe
