Solved ZFS not loading pool in multi-user

Hi,

after reboot I was surprised with a "no pools available to import" error during boottime, leaving my system stuck with a failed /etc/rc script.

I have only one zpool, geli encrypted, pretty much the defaults zfs settings on install.

The problem does not exist in single-user mode and I am able to load my zpool just fine.

Has anybody faced this issue before? Or do you know how to fix this?
 
Is that your encrypted HD from this post?

Solved - Mounting zfs drive from an install key

Hi, I've set some bad options in my /boot/loader.conf and now my system keeps rebooting into kernel panic. I have a 13.1-RELEASE install key and I'd like to mount my zfs drive to /mnt to simply remove a few lines. What is the quickest way of doing this? zpool list gives nothing

Did you export the zpool before using it on the new box?
See zpool-export(8) and zpool-import(8).

Yes indeed it's the same HD but its not a different box, I just went through these steps and this happened when rebooting.

As many details as possible, please. The exact version of FreeBSD, and so on.

Sure. Version is 13.1-RELEASE, installed recently. This happened after loading vboxdrv kernel modules which caused the kernel to fail on reboot. I fixed it by mounting my filesystem with a live iso then this happened.

Single-user mode works correctly but I need to go multi-user on this laptop.

Here is dmesg, though not very helpful:

/boot/loader.conf is pretty normal

This is the last things I've done before rebooting, I simply removed vboxdrv from /boot/loader.conf.

Here's my fstab, but this hasn't changed from when it used to work.

For debugging remove step by step all from /etc/fstab what is not necessary.
Start with removing the last line and then the next last line ...



also try to revert this. In a seperate step.

This had no effects it seems.

Mountpoints seems all fine too

zroot should be /zroot not /

Well done, this was it! Thank you so much, I would have never figured that out by myself.

I must have changed that while messing with the live ISO just before, trying to learn zfs the hard way. I didn't think changes would have been applied to the actual install zfs pool.

Not quite. There should be no mountpoint (or mountpoint none).

From <https://www.freebsd.org/cgi/man.cgi?query=bectl&sektion=8&manpath=FreeBSD+14.0-current>:

Code: 
     … a simplified pool may be laid out as such:

           NAME                    CANMOUNT        MOUNTPOINT
           zroot
           zroot/ROOT              noauto          none
           zroot/ROOT/default      noauto          none
           zroot/usr               off             /usr
           zroot/usr/home          on              /usr/home
           zroot/var               on              /var

Here:

Code: 
% zfs get mountpoint august
NAME    PROPERTY    VALUE       SOURCE
august  mountpoint  none        local
% zfs list -t filesystem | grep ROOT
