I will try -l now. Here is a disk already in the group. It is an identical
disk.
[root]# pvdisplay /dev/sdd1
--- Physical volume ---
PV Name /dev/sdd1
VG Name Scratch
PV Size 33.91 GB [71119692 secs] / NOT usable 4.19 MB [LVM:
161 KB]
PV# 3
PV Status available

Total PE 8680
Free PE 60

I will use its allocated extent size for the new one

The volume is using striping. Is there some issue with that? Do I have to
do some other steps to add the new disk so it is available?
