Why did you mke2fs on /dev/sda2 ? Should have been pvcreate I would imagine.

You could have used fdisk to toggle the partition type when you created 
the partion on /dev/sda2 .

Once again I don't know why you are making/fixing an ext2 file system on 
/dev/sda2 . Try running pvcreate on /dev/sda2 .

Try running pvcreate on /dev/sda2 . That might take care of the above 
problem (only found 6816 of 7424 LEs for LV /dev/Volume00/opt)
