[SOLVED] grub parameters when using proxmox-boot-tool refresh

[Proxygen]

To handle some APST issues with an NVME disk, I need to add

nvme_core.default_ps_max_latency_us=0

to

/etc/default/grub

.

since the system uses

proxmox-boot-tool refresh

, does it read the params in

/etc/default/grub

and if not, how do I add this parameter to the boot process?

Check according to the manual. If your system uses GRUB then it's /etc/default/grub. If your system uses systemd-boot then it's /etc/kernel/cmdline. You can check after a reboot if your change was correctly applied with cat /proc/cmdline.

Thanks. I knew it wasn't using grub. So now /etc/kernel/cmdline looks like

root=ZFS=rpool/ROOT/pve-1 boot=zfs
nvme_core.default_ps_max_latency_us=0

is this correct? I will refresh!

No it is not correct. Everything needs to be on a single line and there needs to be only one line in that file with no empty lines before it. This is also in the manual: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysboot_edit_kernel_cmdline
