Hi.
I have two bootable SSDs, both installed using a GELI encrypted root on
ZFS.
Both use the same passphrase, both boot, if I enter that passphrase at
GELIs prompt.
One contains a GELI encrypted ZFS on root installed using
the 11.1-RELEASE installer, which was source upgraded to 12
(without upgrading the zpools).
The other also contains a GELI encrypted ZFS on root, but installed
using the 11.3-RELEASE installer. This one was source upgraded to
11.3-STABLE r350677.
I'd like to copy over data from the 12 to the 11.3 drive, so I put the
12 one into an external USB enclosure.

root@bsdbuch:~ # geli attach /dev/da0p5
Enter passphrase:
geli: Wrong key for da0p5.
I've then imported the bootpool from da0, and mounted it, so I can try
using the key in boot/
root@bsdbuch:~ # geli attach -k /bootpool/boot/ada0p5.eli /dev/da0p5
Enter passphrase:
geli: Wrong key for da0p5.
If I put the 11.3 drive into the external enclosure, and boot from the
12 drive, I can attach the 11.3 GELI provider without error using the
exact same passphrase (and without using a key)
Am I missing something ?
