LVM on dmraid breakage

[Phillip Susi <psusi@xxxxxxxxxx>]

I am investigating a bug report involving the combination of lvm and 
dmraid, and it seems to me that the problem is that lvm is detecting the 
underlying partition on the primary disk and accessing it directly 
rather than going through the raid device made by dmraid.  I think that 
the problem is there is no facility for dmraid to "claim" the physical 
disk so that lvm does not look at it, and also to have lvm scan the raid 
device for physical volumes.

Does anyone have any thoughts on how this might be accomplished?
