Description Petr Fischer 2018-06-27 06:38:33 UTC
I have encrypted zroot partition, so, my bootpool is separated from zroot zpool. Encryption classic, via GELI, password prompt before boot.

But on freshly updated 10.2, after every reboot, bootpool is not imported, so, no access to the kernel modules, resulting in other related issues (some autoloaded modules from rc.conf, like vbox, can crash the whole system during boot, because bootpool is just not available/auto imported)...

This is similar to bug #212258, but I have GPT (not MBR).

Workaround is probably to import bootpool in rc.local and then, load all necesary kernel modules (like linux, vbox etc.) manualy again (also in rc.local).

This bug occurs probably only on separated bootpool/zroot systems, due to zroot encryption.

Also - I have GPT partitions, but I am booting in CMS BIOS Mode (classic BIOS way), not UEFI, because with UEFI, my i915kms Intel Graphics does not work (tested on 11.0 and 11.1).

Is there any new way how to config encrypted zroot, than separated bootpool/zroot?

Also, after every reboot, this email arrives:
Subject: Cron <root@pf-bsd>    periodic reboot

cannot open 'bootpool': dataset does not exist
        snapshot|snap [-r] [-o property=value] ... <filesystem|volume>@<snap> ...

For the property list, run: zfs set|get

For the delegated permission list, run: zfs allow|unallow

-- End of reboot output --

But bootpool definitely exists, I am importing it manualy (prev comment).
