[SOLVED] Reinstall Proxmox with zfs boot, Can I use exist rpool?

[fcymk2]

I want reinstall my proxmox.
I install proxmox in a zfs pool(2tb*2 mirror0) now.
When I reinstall proxmox, can I only remove the data in /rpool/ROOT and /rpool/ROOT/pve-1 ?
not effect /rpool/data, /rpool/home.

In default proxmox gui install guide, it will destroy the zfs pool . and recreate a new one,

That's right… the installer will wipe the existing zpool out of existence. That's the reason I always separate rpool/boot and vm storage. If you want to save your data, you'd have to zfs send your rpool data ZFS to a file or another zfs host.

Found a way to install it. install Debian Buster Root on ZFS first, and then install proxmox on debian,
