Could it be that there was an old node still around from an unclean volume group removal ? "rm -r /dev/rootvg; vgmknodes" should clean this up for you in case it happens again. > > My setup is this: > 1 on-board SCSI (Adaptec 7880) controller with one disk - sda. > 1 PCI Adaptec 2940UW controller with one disk - sdb. > > sda, Like sdb has 2 partitions.

Because you choose to have a PE size of 16384K and LVM reserves at least 1 PE for future metadata extension.
