[SOLVED] systemd-boot "rootdelay" or ZFS_INITRD_POST_MODPROBE_SLEEP

[QLP24]

Hi,
Just reinstalled 2 hosts in a cluster with PVE 6, mirrored zfs EFI boot. All working fine except the zpool isn't imported right away on boot. About ~5 seconds after it fails to boot (cannot import rpool, no such pool available) all the disks are detected and I can simply do "zpool import rpool; exit" and it boots fine.
This happened with the same host while running PVE 5, but I fixed it with:

rootdelay=10
ZFS_INITRD_POST_MODPROBE_SLEEP=10
ZFS_INITRD_PRE_MOUNTROOT_SLEEP=10

I applied the same fixes to the PVE 6 host, but they don't seem to do anything. I suspected the rootdelay=10 to not do anything since it isn't using GRUB.

* What's the equivalent of rootdelay=10 for systemd-boot? And how do I make that persistent across kernel updates?
* Why isn't ZFS_INITRD_PRE_MOUNTROOT_SLEEP=10 working?


Thank you!

Update: I just found this post: https://forum.proxmox.com/threads/proxmox-6-efi-boot-zfs-rpool-race-to-import-fail.56265/
Am going to test this now. Hope it works.
EDIT: don't have time to test now, will test tomorrow.

Solved: adding 'rootdelay=10' in /etc/kernel/cmdline worked fine.
