Where does LVM store its configuration?

I am trying to understand how / where LVM stores its configuration data.

• Does pvcreate /dev/sdb write any metadata to /dev/sdb? if so what is written?


• Where does vgcreate data /dev/sdb /dev/sdc store configuration of the volume group?


• Where does LVM store the mapping between logical extents and physical extents?


• Is there any machine specific configuration in a LVM configuration?


• Suppose I have machine with 2 disks configured into a logical volume can I just take those disks out the machine and put them in another machine and expect that the logical volume will work in the new machine?
