reinstall proxmox and keep the settings

[mihaib]

Hi all,

I have a noob question: I am currently running 8.4.14 - one single node - everything works perfectly.
Unfortunately I need to reinstall it as my system ssd is almost dead.
I was thinking of installing 9.1 on the new ssd. Now, I have back-ups for all containers and vms.
How can I bkp my storage and network settings? also the Nvidia and HBA driver setup.
Also, I have 2 SSDs where I keep my images and Apps. Is there a way I can import them in the new setup without being forced to format them and loose all data ?

Thank you

you might want to install 9.1. on the new ssd and copy /etc/pve/ from your pve 8.4.14. Then, you could pick parts of your old setting in your new setting, e.g., designated configs relating to storage and network settings

If you back up the following, it should contain the information needed to restore it. Whether you can restore it or not is up to you, so I can't say for sure.

*Programs added via the package manager or compiled using `make` must be configured in the same manner as when originally set up on the disk.

/etc/kernel/cmdline        // boot *Do Not Overwrite. Paste the necessary parts from the file.
/etc/default/grub        // boot *Do Not Overwrite. Paste the necessary parts from the file.

/etc/network/interfaces        // network *Do Not Overwrite. Paste the necessary parts from the file.
/etc/pve/storage.cfg        // storage *Do Not Overwrite. Paste the necessary parts from the file.

/etc/pve/qemu-server/*        // vm config
/etc/pve/lxc/*            // lxc config

/var/lib/vz/snippets/*        // hookscript *After copying, chmod +x * is required.
/etc/modprobe.d/*        // modprobe

/usr/share/kvm/*        // bios/firmware

/etc/modules            // modules
