Hi,
No sure what you want to do with your 2 raid1 arrays... and
why you want to incorporate the first one into LV (?).
Did you partition your second array ? if not, you can create a PV
like this: pvcreate /dev/sdb. "pvcreate" can initialize a disk or partition.
- pvcreate /dev/sdb
- vgcreate vg00 /dev/sdb
Again, no sure what you want to do, but with 4 HD you should consider
to build raid5 (hardware raid) and then create PV, VG, LV.
Regards
