If you're not booting from the array, just make the array the PV. Once you're past the BIOS boot, there's little reason to have partitions at all since you're using LVM to divide the storage into appropriate volumes. If you are booting from it and therefore need partitions, GPT is the new standard for partitions. > i would like that LVM use 1 PV first and then > the second when the first come full (not both at the same time). > Maybe LVM do that by default, or do i need some option ?
