blkid with no arguments only dumps out the cache. We don't actually
verify the devices in that case, as a performance issue. If you have
thousands of fibre channel devices, spinning up all of the volumes
just to verify all of the devices is.... unfortunate.
If you however use blkid to lookup a specific UUID, it will verify
that the information is correct.
So this is working as intended.
