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 : > Hi, > > No sure what you want to do with your 2 raid1 arrays... and > why you want to incorporate the first one into LV (?). > > Did you partition your second array ? if not, you can create a PV > like this: pvcreate /dev/sdb.
