That's not what I know. Might be something with udev or some filtering, but
certainly I was not aware it's related to formatting.
Unfortnately not all disks provide an (stable?) ID. After formatting (at
least with 'pvcreate'), the UUID from the LVM-header is also used for
creating /dev/disk/by-id/... symlinks to the disk/partition.
I'm not so sure about getting the symlinks after formatting with a
filesystem though.
