First, am i planning ugly thing ? is the GPT alternative a better way ? Secondly, I dont know how LVM use PVs within a VG, but for performances issues, 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 ? (i saw "--contiguous" in the lvcreate man pages, but dont know exactly what this option does ... ) Thx C=C3=A9dric
