This has side effect of adding duplicate VG definitions; this may
later
confuse grub. What about just checking array->driver for LVM? Go
through
registered arrays, find disk match and check array driver. See
scan_disk_partition_iter () for example.
Which is basically call grub_diskfilter_get_pv_from_disk() and check
vg_out->driver.
