I am trying to set UEFI kernel boot parameters but its not working. I am running 8.4.19. efibootmgr -v output is:

/etc/kernel/cmd is

I have run proxmox-boot-tool refresh but nothing.

Any suggestions?
 
If your system boots with systemd-boot then you should edit /etc/kernel/cmdline (not /etc/kernel/cmd). If your system boots with GRUB then you should edit /etc/default/grub. If your boot is under the control of proxmox-boot-tool then you need to also run proxmox-boot-tool refresh. The manual will help you determine which bootloader is used and whether it is under the control of proxmox-boot-tool: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysboot

I had a typo in my post. I did edit /etc/kernel/cmdline. I am using systemd-boot and have done proxmox-boot-tool refresh, but the parameters are not being set.
 
I have a mirrored rpool with two disks, when I run proxmox-boot-tool status I get this

Why is one ESP configured with GRUB? Maybe your system is booting from that one? Maybe re-format and re-init it to be sure it is also UEFI and systemd-boot?

The current kernel version does not help in distinguishing since that one is on both. It is weird that the GRUB one has newer kernel versions, which suggest that it has been refreshed more recently.

proxmox-boot-tool refreshes only one of the ESP partitions (which is weird in itself) and it's the one with GRUB. Either Secure Boot is enabled or your are booting in BIOS/legacy mode instead of UEFI (which is influenced by motherboard BIOS/UEFI settings).
I think you need to fix your boot process first so it is GRUB or systemd-boot on both partitions and then your kernel parameters will probably also be fixed.

PS: intel_iommu=on is no longer needed since kernel version 6.8.
 
A second look revealed the issue. Your system is currently booted in UEFI mode but only the GRUB ESP partition is updated.

Maybe try booting the system from the other/GRUB ESP partition (instead of the current UEFI one) or figure out why only that ESP partition is updated.

I removed the disk that had grub, rebooted, ran proxmox-boot-tool refresh, It worked. I am going to format the pulled disk and recreate the rpool mirror and see what happens. Thanks. I will mark this as fixed.

I would assume the drive is fine, including the ZFS mirror (run a scrub to be sure). Just reformat/reinit both ESP partitions using the proxmox-boot-tool format and proxmox-boot-tool init commands (and clean/remove the old partition UUIDs as a format gives it a new one) should probably be enough to get them aligned. I wonder what proxmox-boot-tool status would report afterwards.
