RE: [Xen-devel] AOE (Ata over ethernet) troubles on xen 2.0.6
My setup is:
Server1 - running vanilla debian install + vblade export. vblade is a
userspace app so the kernel doesn't need anything special. A single
partition is being exported, and while it is being used via lvm on the
xen machines, Server1 itself knows nothing about lvm.
Xen1 & Xen2 - running xen 2.0.6 with AoE compiled in. Boot via the
network as they are diskless. Both run lvm on /dev/etherd/e0.0. I need
to take care never to mount the same volume in more than one place. Bad
things happen if I do that (unfortunately I know this from experience!).
My volume names in lvm are things like 'mail-root', 'mail2-root',
'mail-swap', etc. the xen0 domains export those volumes to the other
domains. The other domains don't use AoE directly. Migration works well
as both xen machines can see all the lvm volumes.
One of the xen machines has a 1Gb network adapter and a 100Mb adapter.
The 1G has no ip address and is simply used for AoE. The other network
adapter uses vlan's to service 3 other networks.
The other xen machine has only two 100Mb adapters but is otherwise
configured much the same.
Hope that tells you what you want to know!
