Can you provide more details. What was your boot device? (PXE??, SATA HDD, RAID controller, etc.)

 

[fusion]

Raid 0 controller. (Ahci)

Hi fusion,

the server is booting from ethernet connection, try to boot to hard drive from bios.

in the bios, can you see hard disks?

 

[fusion]

boot hard disk.

Try to boot with a rescue CD, then mount your drives, chroot and run again update-grub

( i.e.: system-rescue-cd )

I followed these steps, all right, but the problem remains.

zpool import -R /mnt rpool
mount -t proc /proc /mnt/proc
mount --rbind /dev /mnt/dev
mount --rbind /sys /mnt/sys
chroot /mnt bin/bash
grub-install /dev/sda
update-grub2
update-initramfs -u

 

[Marco Manenti]

/etc/default/grub try add rootdelay
GRUB_CMDLINE_LINUX="root=ZFS=rpool/ROOT/pve-1 boot=zfs rootdelay=20"

/etc/default/zfs try add
ZFS_INITRD_PRE_MOUNTROOT_SLEEP='10'
and
ZFS_INITRD_POST_MODPROBE_SLEEP='10'

 

[fusion]

same error: (

 

[Marco Manenti]

hmmm why update-grub2 ? i'm using grub here..
it seems it doesn't see zfs ... do you have pve 5.1 with zfs?
could you see your data from rescue cd?

 

[fusion]

yes proxmox 5.1 with zfs

update-grub

 

[Marco Manenti]

Ok, and then? does it boots?

look at this:

and this:

[fusion]

still doesn't start the same error, I've tried everything: (

 

[Marco Manenti]

it seems an hardware problem described in the proxmox wiki...
could you export with zfs-send the pools to another machine?
My knowdedge stops here.. :-/
