Kaloyan: I can't get Oracle VM to look at the Logical Volume either (building a lv on drbd was dirt-simple). I think I'm hosed. I'll return to the Oracle forum and see what they say about LVM, but unless I can get the drbd resource to be presented by multipath, I don't think Oracle VM will use it.
Thanks for the help, none the less.

Another option is LVM over DRBD -> device in /dev/mapper Another one is just a symlink in /dev/mapper from udev rule On Tue, 10 Apr 2012 09:41:13 -0400, "Dan Barker" <[email protected]> wrote: > How do I get multipathd to notice my drbd block devices? > > RHEL5 (Oracle VM 3.0.3.127, actually), 2.6.32.21-45xen. > Drbd 8.4.1: > multipath-tools says v0.4.9.
