It was 384 and it is now 3072. I tried using --metadatasize > 192k --dataalignmentsize 0 and it did not help. What gives? Try to set default_data_alignment = 0 from lvm.conf: # Default alignment of the start of a data area in MB. If set to 0, # a value of 64KB will be used. Set to 1 for 1MiB, 2 for 2MiB, etc. Also, if you use pvcreate --uuid <pv uuid from metadata> --restorefile <old VG backup> it should create PV exacltly as needed for olf VG (with --restorefile it uses offset from metadata backup, overriding default) Then vgcfgrestore and you should have exactly the same cfg.
