xen + raid1

[aqua]

Hello All:

I am installing the Xen/vserver howto as described by falko (excellent howto by the way!).

I am installing this setup on a pair of external harddrives, which i have setup as a software RAID1. Here is a copy of mdadm --detail /dev/md0

mdadm --detail /dev/md0

/dev/md0:

1 8 17 1 active sync /dev/sdb1


so now my question is, how should my /boot/grub/menu.lst look like?
i tried several variations, but my computer either keeps rebooting or gets stuck on start up:

title Xen 3.0.1 / XenLinux 2.6.12-xen0
root (md0,0)
kernel /boot/xen.gz dom0_mem=65536
module /boot/vmlinuz-2.6-xen0 root=/dev/md0 ro console=tty0

thank you

Please post your /etc/fstab here.

here is the file you requested...

GNU nano 1.2.4 File: /etc/fstab

# /etc/fstab: static file system information.

Please try this in /boot/grub/menu.lst:

title Xen 3.0.1 / XenLinux 2.6.12-xen0
root (hd0,0)
kernel /boot/xen.gz dom0_mem=65536
module /boot/vmlinuz-2.6-xen0 root=/dev/md0 ro console=tty0

i tried that...it would start the booting process, but it would reboot halfway through it.... any other suggestions?

[falko]

Can you recall the error message that appears before it reboots?

[aqua]

I didn't see an error just before it rebooted...but the last line i recall just before it rebooted is something like:

Initializing full-speed usb...the screen goes by pretty quick so I don't know the exact line...

[aqua]

Do you think i might have to enable RAID support when i compile Xen?

[falko]

I'm not sure, but you can try at least...
(Did you know that I spent a whole week to compile my first kernel the way I wanted it? Weird... :( )

[aqua]

I guess i will go with that route instead...so then...how do i delete my old configuration so i start fresh? it it enough to delete /boot/xen.gz?

[falko]

You don't need to delete anything. Just start over.
