[Xen-users] Xen & DRBD

[Stuart Poulton <swp@xxxxxxxxxxxxxx>]

Dear All,

I'm using drbd to provide a HA pair of servers to run xen domains on.

I've created a test domain as follows

x-host-2:~ # more /etc/xen/vm/opensuse
name="opensuse"
ostype="opensuse"
uuid="ee62226a-8487-cc02-d89f-dafafd1f35e6"
memory=1214
vcpus=2
on_crash="destroy"
on_poweroff="destroy"
on_reboot="restart"
localtime=0
builder="linux"
bootloader="/usr/lib/xen/boot/domUloader.py"
bootargs="--entry=xvda1:/boot/vmlinuz-xen,/boot/initrd-xen"
extra=" "
disk=[ 'phy:/dev/drbd0,xvda,w',]
vif=[ 'mac=00:16:3e:29:fb:80', ]
vfb=['type=vnc,vncunused=1']

This works fine, and start and stop the domain on both of the nodes.
However if I try to use

disk=[ 'drbd:xendomains,xvda,w',]

I get the following error....

x-host-2:~ # xm create opensuse
Using config file "/etc/xen/vm/opensuse".
Error: Disk isn't accessible

I'm expecting the block-drbd script to do something here, but from what
I can tell it's not.

I suspect I've missed something fundamental. Any pointers please ?

Thanks

Stuart
