I'm sorry. My explanation was not good. Only PV1-3 are updated and
PV4-6 are not. LVM command have always behaved like this.
I should have added an more sentence like
If we create a new LV or delete VG1, then metadatas on only PV1, PV2, PV3
need to be updated but not for PV4, PV5, PV6. So PV4-6 don't necessarily
need to be accessed.
Sorry for making you confused.
Thanks,
