You can just add c0d0p3, run pvcreate on it: pvcreate /dev/cciss/c0d0p3 then: vgextend VolGroup00 /dev/cciss/c0d0p3 Since all of the partitions end up in the pool called VolGroup00 anyway, it makes no difference if there's one large paritition or two smaller ones. Once they are part of VolGroup00 you just work with the group without ever thinking about partitions again. -- Ray Morris support@bettercgi.com Strongbox - The next generation in site security: http://www.bettercgi.com/strongbox/ Throttlebox - Intelligent Bandwidth Control http://www.bettercgi.com/throttlebox/ Strongbox / Throttlebox affiliate program: http://www.bettercgi.com/affiliates/user/register.php On Thu, 22 Sep 2011 14:46:08 +0200 Michaël Berger <miberger79@gmail.com> wrote: > aha: that is something: > > > Command (m for help): v > 286690436 unallocated sectors > > Command (m for help): n > > Probably I need to add that the c0d0p2 with fdisk first > > On Thu, Sep 22, 2011 at 2:32 PM, Michaël Berger > <miberger79@gmail.com>wrote: > > > Hello, > > > > I am very new to LVM.
