Hi,
I want to create an USB stick with Solaris that can be booted on bare
metal and in a QEMU virtual machine -- but it does not work as expected:
I can boot the USB stick in QEMU but I can not boot it on bare metal.
Booting the USB stick on bare metail always leads to the error message
error reading device labels
....
spa_import_rootpool: error 22
panic : cannot mount rootpath
...
What I've done until now:
1. boot the Milax CD (Solaris snv95) in QEMU/kvm (under Linux) using
sudo kvm -net user -usb -usbdevice tablet -L /usr/share/qemu -m 512
-net nic -redir tcp:1135::22 -name "Milax" \
-hda /dev/sdb -cdrom /data/nobackup/iso/milax.iso -boot d
and install Solaris snv95 (Milax) with the zfsinstall script from
Milax on the USB stick
(-> /dev/sdb in Linux is the USB stick; in QEMU the USB stick is a
normal harddisk for Solaris)
2. after the installation finished I created the signature file for
the grub command findroot:
(root at milax)# ls -l /milaxusb/boot/grub/bootsign/pool_milaxusb
-rw-r--r-- 1 root root 0 Oct 31 10:27
/milaxusb/boot/grub/bootsign/pool_milaxusb
and added the findroot command to the grub menu entries:
title MilaX 0.3.2 (32 bit)
findroot pool_milaxusb
kernel$ /platform/i86pc/kernel/unix -B $ZFS-BOOTFS,console=text
module$ /platform/i86pc/boot_archive
3. Then I shutdown the virtual machine, attached the USB stick to a
machine running Solars snv_101 and installed the grub
from that Solaris version on the USB stick using installgrub
installgrub -m /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c3t0d0s1
Now I can boot the USB stick in QEMU but I can not boot it on bare metal.
I already tested the following work around which I found via google:
Boot the machine from the Milax CD, attach the USB stick, and import the
ZFS pool. It seems that this solutions destroys the grub configuration
on the USB stick because after doing this I can not boot the USB stick
anymore (neither in QEMU nor on bare metal). The booting always
ends in the grub shell (-> no grub menu is shown).
My understanding of the findroot command is, that it checks for the
signature file and uses the disk on which it finds the file as root disk
for Solaris (independent from the type of the disk)
So I think the configuration should work as expected -- or do I miss
something here?
