Solution:
Unfortuantely that probably means you reached the maximum number of PV allowed for this Volume Group.

do a
#vgdisplay -v indrtest|more

and check that your Max PV is higher than the Cur PV. If they are equal (which is what I think is happening right now), that means you cannot add any more disks into that VG.

You either have to create a new VG, or re-create this current VG with option -p to have more disks than the actual value.
Cooperation is doing with a smile what you have to do anyhow.
