Hello and thanks for the answer.
For "political" (indeed) reasons, we can't use the raid 5......
and there is a partition using the whole second "disk" (ie raid array),
it is sdb 1. When I type the command pvcreate /dev/sdb or /dev/sdb1
i get the following message....device /dev/sdb1 not found or ignored by
filtering
xdub a �crit :
