vgcreate confused by PVs on whole disk

[Louis Guillaume <louis%zabrico.com@localhost>]

Hi,

I'm trying to create a volume group with 2 disk members that are 
available to my system. There's no need for bootability, so I'm using 
the whole raw disk partition. When it gets to "vgcreate" I get an error 
like this:

  Found duplicate PV 5ei5O3Q1MfECIBfK52fKHotRoHhntt2v: using 
/dev/rxbd1d not /dev/rxbd1a
  /dev/rxbd2e: open failed: Device not configured


The VG is still created, but the message makes me nervous. Is this 
message as serious as it sounds?

Details about the setup are below. Any help would be great. Thanks!


Louis
