ZFS mounts dont come up after kernel 6.8.8-2 update

[lopiuh]

I have a ZFS on deban bookworm installation link after last kernel update and a reboot several ZFS mounts did not came up (e.g. /var/log). after zfs mount -a and a reboot they come up. Has anybody why they did not came up? maybe no coincidence with the kernel update.

is reproduceable, anyone interested in debugging with me?

syslog says: local-fs.target: Job zfs-mount.service/start deleted to break ordering cycle starting with local-fs.target/start

I suppose

https://github.com/openzfs/zfs/issues/14010
https://github.com/zfsonlinux/pkg-zfs/issues/205

has to do something with it

It seems to be a temporary issue after upgrading (for me unknown) packages. After a reboot the "zfs datasets not mounted after reboot" issue went away. I placed a check in my installer script to identify the situation and it triggers only once after installing the base packages. Maybe you could do a crosslink to this Thread in: Install Proxmox VE on Debian 12 Bookworm

if uname -a | grep "pve" > /dev/null; then
    # Wir laufen bereits unter pve-kernel. Beim ersten Start des pve kernels (oder weil ein starker Versionssprung erfolgte) fehlen zfs mounts (siehe https://forum.proxmox.com/threads/zfs-mounts-dont-come-up-after-kernel-6-8-8-2-update.149934/)
    # deshalb (etwas dirty) gucken, ob alle mounts da sind
    for _item in $(cut -f 1  /etc/zfs/zfs-list.cache/rpool); do
        if ! zfs mount | grep -q "$_item"; then
            echo "Wir laufen bereits unter pve-kernel. Beim ersten Start des pve kernels (oder weil ein starker Versionssprung erfolgte) fehlen zfs mounts (siehe https://forum.proxmox.com/threads/zfs-mounts-dont-come-up-after-kernel-6-8-8-2-update.149934/)"
            echo "Es fehlt der mount: ${_item}, Reboot?"
            echo -n "hit return to Reboor or CTRL-C!"; read x; echo "continuing..."
            systemctl reboot
            exit
        fi
    done
    unset _item
fi

the problems seem to be ZFS related, see https://zfsonlinux.topicbox.com/groups/zfs-discuss/T9c0db0309540e0f8 for a solution
