Change zfs boot pool name

[RealPjotr]

Hi. I'm adding a new node to my Proxmox cluster where all earlier nodes use the boot disks for VM storage. I've setup HA syncing via the ZFS rpool.

Now I want to add another node, but I want to have rpool on separate data disks, not the boot media. I've managed to rename the boot disk rpool to spool ok, so now Promox fails to boot because /proc/cmdline looks like this:

initrd=\EFI\proxmox\6.8.4-2-pve\initrd.img-6.8.4-2-pve root=ZFS=rpool/ROOT/pve-1 boot=zfs

I get stuck in initramfs and have trouble editing this file. How can I do this?

You can't edit that file. It just gives you a read-only copy to show the command line that was passed to the kernel by the boot loader. At this point, even if you were able to modify it, it's already too late. The kernel has processed all that information.

You probably need to edit /etc/kernel/cmdline and then you have to rebuild all the boot loader files. Usually, this involves executing the proxmox-boot-tool from the running system.

You can in principle do this from the within the initramfs rescue shell. But it's a bit tedious. I am not sure how to walk you through the steps without having access to your computer to keep checking things.
