That is usually caused by a partition which has had a pv header (from using
pvcreate) and then later used for a filesystem. The result is often that
the pv header is only partially overwritten by the fs.
Right, I initially created a LVM partition at the beginning of the disk,
then went back to change the first into a small /boot partition and put
the LVM partition after that.
So it is sda1 which is recognized as a pv.
How can I fix it?
Normally you'd have to run pvremove on /dev/sda1, the problem is that it
will wipe the beginning of the partition (first 2k I think), so if
you're going to do that, you have to move the data off it, umount,
pvremove, mkfs, mount, move data back, re-install grub or lilo into the
partition header/MBR.
Alternatively you could use a hexeditor and look for the LVM signature
"LVM2 001" on the partion and replace that with zero's...if you're feeling
adventurous
