from what i can remember, pvcreate should be unable (without "force") to create a physical volume on an entire disk if there was a partition table on that disk. something must have changed because now it seems it doesnt even check, and worse, it doesnt remove the partition table. what happens is you end up with a pv on the entire disk as well as a partition table on the disk. here are some details: [root@linuxclone root]# lvm version LVM version: 2.00.15 (2004-04-19) Library version: 1.00.14-ioctl (2004-04-06) Driver version: 4.1.0 distribution: fedora core 2 pvscan shows 2 pv's, one on the entire disk the other on a partition on the same disk. how can that happen?
