old boot zfs usb stick keys and db recovery!

[Radu]

I have the old stick mounted in a new freenas instalation:

[root@fns] /mnt/test# zpool status oldboot
pool: oldboot
state: DEGRADED
status: The pool is formatted using a legacy on-disk format. The pool can
still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'. Once this is done, the
pool will no longer be accessible on software that does not support feature
flags.

The mount was succesful with:

state: DEGRADED
status: One or more devices were being resilvered.
action: The pool can be imported despite missing or damaged devices. The
fault tolerance of the pool may be compromised if imported.

What is the question? Or have you sorted this?

I did actually.
On freenas 9.3 live boot instance the USB sticks have resilvered and i was able to obtain the keys from the gui.
Prior to resilvering, I have tried to mount the stick that was good, importing the zpool with -f and with different name. Importing was succesful but after the mount there was no data available.

DO MAKE BACKUP'S OF YOUR KEYS AND RECOVERY KEYS !
