Volume Groups still exist after reinstall

[lr23]

Hi
I have a two Node cluster with LVM on top of iSCSI.
I reinstalled my Proxmox environment a few days ago. Since it was just a test environment and there was no sensitive data on the hosts, I just reinstalled Proxmox and did not delete the disk. But I deleted the old array as it is not recommended by Proxmox to use a hardware raid controller (anyone know why?) and I thought that should be enough. I thought Proxmox deletes the entire disk when reinstalling. But when I checked, my LVM volume groups were still there. Does Proxmox not delete the disks? Or are these VG configurations stored somewhere else? I was able to destroy those VGs and create new VGs with my LUNs. But still I wonder why the VGs were still there.

This, I believe, is specific to specific file systems, i.e. ZFS and/or Ceph.

Does Proxmox not delete the disks?

Unless you force it, the partitions/signatures/etc on non-OS drives will not be deleted.

Or are these VG configurations stored somewhere else?

VG signatures are stored on the disks themselves. This is independent of PVE.
