[linux-lvm] duplicate PV error with 2.6.1 and lvm2

[David Powers]

I am attempting to create a simple volume on a soft raid 1 device 
(/dev/md1) on a gentoo linux box running 2.6.1.  The pvcreate seems to 
go fine but when I then attempt to create the volume group I get an odd 
error about duplicate PV's.  It seems as if the code is sometimes 
treating the device as a single device and sometimes seeing the 
underlying disks.  Any help would be appreciated.
