I have an ancient Proxmox server running 3.2-4 with the following packages versions:

Code: 
proxmox-ve-2.6.32: 3.2-126 (running kernel: 2.6.32-29-pve)
pve-manager: 3.2-4 (running version: 3.2-4/e24a91c1)
pve-kernel-2.6.32-29-pve: 2.6.32-126
lvm2: 2.02.98-pve4
clvm: 2.02.98-pve4
corosync-pve: 1.4.5-1
openais-pve: 1.1.4-3
libqb0: 0.11.1-2
redhat-cluster-pve: 3.2.0-2
resource-agents-pve: 3.9.2-4
fence-agents-pve: 4.0.5-1
pve-cluster: 3.0-12
qemu-server: 3.1-16
pve-firmware: 1.1-3
libpve-common-perl: 3.0-18
libpve-access-control: 3.0-11
libpve-storage-perl: 3.0-19
pve-libspice-server1: 0.12.4-3
vncterm: 1.1-6
vzctl: 4.0-1pve5
vzprocps: 2.0.11-2
vzquota: 3.1-2
pve-qemu-kvm: 1.7-8
ksm-control-daemon: 1.1-1
glusterfs-client: 3.4.2-1

This server is behind a strong FW and currently has no internet connectivity. However, I'm making some networking changes and need to upgrade this server to latest PVE release for both performance & security reasons. After all, it has not been updated in over 5 years!

It is running with a IBM M5016 serveraid controller and LVM

  1. How can I upgrade this server to latest PVE release without losing any of the underlying hardware config (LVM, partitions, fstab, etc)?
  2. Will I lose the VM images ?
  3. Should I simply backup the VM's to a different server, wipe everything on the PVE server then reinstall fresh with USB or DVD?

you can follow the wiki instructions [0] [1] [2] [3]

not if you make backups ;)

yes, might be a simpler approach to do that and import/restore the VMs afterwards

Upgrade to 7.0 went smooth, but re-adding existing LV's to the VM's would have been difficult to do without looking in the qemu-server/VMID.conf files to remember how I got this up & running back in 2014.... :)

I couldnt find a way to detect the LV's from the WebUI and add them to VM's. The WebUI listed the top level VG but not the underlying LV's.

can you see the LVs from lvs -a? you should check your /etc/pve/storage.cfg file (that's where the storages on the GUI are defined)
 
Hello Oguz, yes I see them: they are highperf_lv1 to lv3

What I find weird is that after installing PVE 7.0 the storage.cfg had NO reference to the LV's but only contained a single entry for the VG. Here's the original storage.cfg (right after installing PVE7):

Code: 
dir: local
        path /var/lib/vz
        content vztmpl,backup,iso

lvmthin: local-lvm
        thinpool data
        vgname pve
        content images,rootdir

nfs: pve-backup
        export /mnt/zpool/pve-backups
        path /mnt/pve/pve-backup
        server freenas
        content backup
        prune-backups keep-all=1

lvm: highperf
        vgname highperf
        content images
        shared 0

Here's the storage.cfg now (after I modified it to manually add the LV's):
Code: 
dir: local
    path /var/lib/vz
    content vztmpl,backup,iso

lvmthin: local-lvm
    thinpool data
    vgname pve
    content images,rootdir

nfs: pve-backup
    export /mnt/zpool/pve-backups
    path /mnt/pve/pve-backup
    server freenas
    content backup
    prune-backups keep-all=1

lvm: highperf_lv1
    vgname highperf
    content images
    nodes proxmox

lvm: highperf_lv3
    vgname highperf
    content images

lvm: highperf_lv2
    vgname highperf
    content images

You see the PVE installer seems not to have detected the LV's properly and had assigned the VG name to the LV (highperf).

Now the LV's are shown in the WebUI and lv1 is attached (in VMID.conf) to a specific VM and works just fine. The other LV's are not used...
