My domU reboots fine when i use:

  disk = ['phy:/dev/xen/samba-ha,hda1,w','phy:/dev/xen/samba-ha-fs,hdb,w']

Isn't /dev/hda2 supposed to work too?

Hi,

Setup: xen-unstable (last hg pull -u: 2005-08-20 21:51)
Dom0, debian 3.1 amd64 testing/unstable
DomU, debian 3.1 amd64 stable

I have a setup in which i have a rootfs for domU on lvm (/dev/xen/samba-ha)
and a datafs (which is going to be used in domU to store samba data on, it's 
currently empty , but a valid ext3 filesystem) on lvm (/dev/xen/samba-ha-fs)

I configured them in my /etc/xen/samba-ha:
disk = ['phy:/dev/xen/samba-ha,hda1,w','phy:/dev/xen/samba-ha-fs,hda2,w'] 

In my fstab on my domU (samba-ha) i have:

  /dev/hda2       /fs             ext3   defaults         0       1
In my current setup i don't do anything with /dev/hda2, i don't mount it, i don't use it.
When i reboot this domU (samba-ha) it does not reboot. It stops at "Rebooting System" 
and returns to the dom0 prompt.

See bottom of mail for xend.log.
I isolated the problem to the adding of the phy:/dev/xen/samba-ha-fs as hda2. 
If i don't use that LVM disk as hda2 it reboots fine.

What am i doing wrong? Or is this a bug?
