[SOLVED] Cluster Updating 5x to 6x

[killmasta93]

Hi,
Recently doing a test to upgrade my test lab from 5x to 6x following the steps from the WIKI everything went well but installing proxmox 6 and rebooting i get the error on busy box undefined symbol: efi_rescan not sure what means. all of my 3 hosts had ZFS
i tried importing manually but didnt work keeps showing that error
Thank you

seems something went wrong during the upgrade - and you did end up with the wrong zfs userspace packages

-> boot a live-CD with ZFS support (or start the PVE installer in debug mode - the second debug shell should have ZFS utilities present)
-> check which versions of the relevant packages are installed (pveversion -v ) for zfs the following packages should be all in the same version:

ii  libnvpair1linux                       0.8.5-pve1                    amd64        Solaris name-value library for Linux
ii  libuutil1linux                        0.8.5-pve1                    amd64        Solaris userland utility library for Linux
ii  libzfs2linux                          0.8.5-pve1                    amd64        OpenZFS filesystem library for Linux
ii  libzfslinux-dev                       0.8.5-pve1                    amd64        OpenZFS filesystem development files for Linux
ii  libzpool2linux                        0.8.5-pve1                    amd64        OpenZFS pool library for Linux
ii  python3-pyzfs                         0.8.5-pve1                    amd64        wrapper for libzfs_core C library
ii  spl                                   0.8.5-pve1                    all          Solaris Porting Layer user-space utilities for Linux (dummy)
ii  zfs-dbg                               0.8.5-pve1                    amd64        Debugging symbols for OpenZFS userland libraries and tools
ii  zfs-initramfs                         0.8.5-pve1                    all          OpenZFS root filesystem capabilities for Linux - initramfs
ii  zfs-test                              0.8.5-pve1                    amd64        OpenZFS test infrastructure and support scripts
ii  zfs-zed                               0.8.5-pve1                    amd64        OpenZFS Event Daemon
ii  zfsutils-linux                        0.8.5-pve1                    amd64        command-line tools to manage OpenZFS filesystems

I hope this helps!

sorry - I did not say that explicit enough:
once inside the installer debug shell you need to chroot into your live-system and then run the commands inside the chroot

roughly and without testing it this should be the steps:
* zpool import with and alt-root set
* bind-mount /proc, /sys, /dev, /dev/pts, into the root
* chroot inside
* run `dpkg -l |grep -i zfs'
* run `dpkg -l |grep <the version of zfsutils-linux`

there should be tons of howtos on the internet for the bindmounts and chroot

I hope this helps!
