Michael, the pvdata output below exposes a completely messy PV structure, which makes me think of 2 possible reasons: a. /dev/hda2 is not the device you used to create a physical volume b. something accidentially overwrote /dev/hda2 after the PV creation If b is true you might still have an actual VGDA backup in /etc/lvmconf/ which you can use to vgcfgrestore(8) it to /dev/hda2 presumed that /dev/hda2 is the right device.
