Currently I have a strange situation when I have running system on my zroot
but I can't import this pool when booted from memstick. I was trying to
understand what is going on and here are my observations. My partition table
is:
gpart show -l
= 34 250069613 ada0 GPT (119G)
34128 1 (null) (64k)
162 1886 5 (null) (943k)
2048 16777216 2 linux0 (8.0G)
16779264 33554432 3 home0 (16G)
50333696 199735951 4 disk0 (95G)
but in /dev/gpt I only see:
ls /dev/gpt/*
/dev/gpt/home0 /dev/gpt/home0.eli /dev/gpt/linux0
(home is encrypted).
I have a regular system installed and running on this pool. Filesystem to
boot from is called 'zroot' and it can only boot when my whole loader.conf
is used. With only zfs.ko booting stops with boot prompt asking for
filesystem to boot from, menu shows all my gpt partitions and id's correctly
so I don't understand why it can't find it.
Below is my loader.conf:
