You don't need to expand sda3 really. You can just create a new 
partition, create a new PV with it and add the new PV to pve VG.

I don't know really how to reply to this. If you're building a cluster, 
I suggest you configure some kind of shared storage; NFS server or Ceph 
cluster for example.

For what?

Maybe you can start telling us your target use for this server/cluster. 
Also some detailed spec of the server would help; for example does it 
have a RAID card with more than one disk, or you're using a 6TB single disk?

Cheers
