Hi,
I''m trying to do a HA cluster with xen, drbd and HeartBeat.
I use : Debian Etch, Xen 3.0, LVM2, DRBD0.7 and heartbeat v1
My architecture is :
IP public IP public
| |
| |
-------------- --------------
| node1 | -- -- -- Crossover -- -- -- -- | node2 |
-------------- --------------
There is a DRBD on node1 and node2. On Drbd there is LVM.
On LVM there is Virtual Xen Machines ...
Well, When I disconnect the crossover cable ... Less tha one minutes (but not
immediatly), there is a kernel panic. It''s about interruption ...
This apend "only" when there is some DomU on Xen.
So I''ve tried different configuration :
- only drbd/lvm with a vanilla Debian kernel : it''s ok,
didn''t crash
- only drbd/lvm with a xen Debian kernel : it''s ok, didn''t
crash
- only xend hypervisor, drbd/lvm with xen Debian Kernel : it''s ok,
didn''t
crash
- xend hypervisor, 2 domU, drbd/lvm : crash ;''(
- xend hypervisior, 2 dom, drbd/lvm but with noapic nolapic acpi=off on dom0
grub : crash :''(
any idea ? any questions ?
thanks in advance
(I will come back with a Debian Testing + xen3.1 ...)
