Proxmox5.2 does not use all local space by default

Hello,
I have a 2 node/2 socket subscription cluster that I am moving from Proxmox4.4 to Proxmox5.2 as 4.4 is EOL Each node has a 4TB disk and I have some shared NFS storage. I moved all VMs to node 2, removed node 1 from cluster and installed 5.2 on node 1. However, the local storage of node 1 now only has 100GB. lvdisplay shows a 3.5TB volume named data, but this is not automatically added to local for use. Comparing nodes, I noticed that node 2 mounts /dev/mapper/pve-data to /var/lib/vz but node 1 does not.
Did the 5.2 installer ignore the data volume because it might contain useful data? If so, I will reinstall and after zeroing the disk. If it normal to leave the unneeded disk area unused, then what is the preferred way to use it? Should I just add the mount to fstab like node 2 or something else?

Thanks,

Thanks Dietmar! I did not see local-lvm listed as a storage option on the host. Only saw local (100GB) and some NFS shared storage that I use. I am going to rebuild the host again and check for local-lvm before I add it to the old cluster. I will let you know what I discover.
Thanks,
Dale
 
OK, that makes sense. Would it be possible to move all guests to node B, remove that node from the cluster, build new node A and new cluster, and then add node B to new cluster? If so, then node A should retain local-lvm, right?
 
I suppose another option would be to move all guests to node B and move them to shared NFS storage, remove node A from cluster, rebuild node A as standalone server with same shared storage as old cluster, power down guests on node B, power up guests on node A server, then poweroff and rebuild node B, then create new cluster. Thoughts?
 
I was able to use all the local space by building a new 5.2 Proxmox server with the same shared storage as the old 4.4 server. Then I backed up guests on the old server to shared storage. Then I powered off the guest and restored from backup on the new server. Once I verified the guests worked, I deleted the old server and rebuilt with 5.2
