Drives not showing when sudo pvdisplay
7,550
pvs
doesn’t list physical drives, it lists physical volumes. You need to create a physical volume before it will appear in pvs
’ output:
pvcreate /dev/sdc
or
pvcreate /dev/sdc1
(the latter if you’ve partitioned the drive).

I'm going to make a RAID5 setup on my ubuntu 14.04 server. I had 2 4 TB WD NAS drive and have purchased another. However, when I try to find those drives in my system using pvs, I only find 3 drives (my system drive and two additional drives).

So the sdc drive isn't showing in pvs. Is this something to be concerned about before making the RAID, or shall I just move on?
Thanks in advance.. :)
