xen + raid1

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.

 

/etc/fstab

Hrllo falko:

here is the file you requested...

GNU nano 1.2.4 File: /etc/fstab

# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/md0 / ext3 defaults,errors=remount-ro 0 1
/dev/hdb /media/cdrom0 iso9660 ro,user,noauto 0 0
/dev/hdd /media/cdrom1 iso9660 ro,user,noauto 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto 0 0
/dev/sda /media/usb0 auto rw,user,noauto 0 0
/dev/sdb /media/usb1 auto rw,user,noauto 0 0

 

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

Code:

title Xen 3.0.1 / XenLinux 2.6.12-xen0
[B][COLOR="Red"]root (hd0,0)[/COLOR][/B]
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?

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

 

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...

 

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

 

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... )

 

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?

 

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