How to increase the maximal number of partitions ?

[Jean-Philippe BATTU]

Hello

on a linux box, I use parted over a 800Gb array raid 5 disks. I would like to store in this array, about 20 partitions of 30 Go each.

I create all these partitions with parted without any problem, primary, extended and logical as follow:

GNU Parted 1.8.1
Using /dev/sdd

(parted) q                                                               

when I exit from parted, only the first sixteenth partitions have been created. How to say to the linux system to create more than 16 devices for my logical volumes ?

thanks for your help
