LVM does not currently have multipath support. It is planned for inclusion into LVM or possibly a separate driver to stack with LVM after LVM 1.0 is released. We are currently too busy dealing with trying to get a stable LVM release out to start adding new features now, but hopefully multipathing and other highly requested features will be supported soon. For now it sounds like the best option is to patch MD to support multipathing and stack LVM on top of that. Regards, --=20 AJ Lewis Sistina Software Inc.
