[TUTORIAL] UEFI boot ZFS

[killmasta93]

Hi,
Just wanted to post back if someone else gets this issue, as i was trying to configure HP server ml 350 gen9 with HBA card LSI i could not get it to boot on legacy, So i had to boot with UEFI, I went with the lasted version on proxmox. But it wont boot up after i ran zpool import rpool and it booted up but then i rebooted, cannot import rpool so i went to the grub
/etc/default/grub
then inside of the line linux default
to root delay=10 quiet

then i also had to run this

echo -n " rootdelay=15" >> /etc/kernel/cmdline

pve-efiboot-tool refresh

and works flawless

This is also described in the wiki - https://pve.proxmox.com/wiki/ZFS:_Tips_and_Tricks#Boot_fails_and_goes_into_busybox
