Hi all,
I noticed this message during boot time spa_load($import, config untrusted). It happens when zfs try to import two mirrored SSD pools:


Code:

Prigioni and VMStore are used for jail and bhyve VMs respectively, while Edge0 is the storage pool, always "trusted".

What's the meaning of that message?

Maybe, but I could be wrong : - )

I've found this comment here https://github.com/freebsd/freebsd/...5d36785#diff-b164f50a536f32f0b3500bae4fc1f2ae

Code:
[...]a new approach has been adopted:
The pool is first opened with the untrusted userland configuration just so that
the real configuration can be read from the MOS. The trusted MOS configuration
is then used to generate a new vdev tree and the pool is re-opened.

When the pool is opened with an untrusted configuration, writes are disabled
to avoid accidentally damaging it.[...]


I shouldn't look at the console during boot time!
