OK, so I have cleared everything off my /dev/sda (except, presumably,
the MBR) and all is well still, Fedora still boots and my Windows
guest virtual machine is still working.
How do I now set up /dev/sda using LVM? As I understand it the
sequence is to create a Physical Volume using pvcreate, then a Logical
Group that uses the Physical Volumes I have created and then I create
a logical volume in the Logical Group.
The problem is that I don't understand how you tell pvcreate what disk
it is to use. The 'synopsis' on the pvcreate man page says:-
SYNOPSIS
pvcreate [-d|--debug] [-f[f]|--force [--force]] [-y|--yes] [-h|--help] [-t|--test]
[-v|--verbose] [--labelsector] [-M|--metadatatypetype] [--metadatacopies#copies] [--meta-
datasizesize] [--restorefilefile] [--setphysicalvolumesizesize] [--version] [-Z|--zeroy/n]
PhysicalVolume [PhysicalVolume...]
Which doesn't seem to give much clue as to what disk it uses,
PhysicalVolume is (as I understand it) the name that pvcreate gives to
the chunk of disk you want to use, so what disk does it use?
