ZFS pool "gets lost" when server is unplugged from power

Hi all,
I am having a strange problem. Whenever my server loses power (either power loss or the power socket is switched off) a zpool "disappears" or is not mounted/imported in Proxmox on the next reboot and I have to import it manually via CLI (zpool import ...). When I shutdown the server without switching the power socket off the zpool is available on the next reboot.

I created the respective zpool on a SSD but did not add it to Proxmox as storage. Instead it is a bindmount to a Turnkey file server (as LXC).

What do I have to do to make the zpool import survive a power loss?

Thanks for your assistance :)

After you zpool import it, does it show up in zdb -C? Anything relevant in the logs (e.g. journalctl -u 'zfs*')? Maybe also look at zpool get cachefile to see if anything's funky.
