FreeBSD:
I have a FreeBSD 11.0 i386 machine with encrypted ZFS on root and
encrypted swap as created by the FreeBSD installer. I would like to
change the root password. I issued the following command:
toor@freebsd:/root # geli setkey -n 0 /dev/ada0s1d
Enter new passphrase:
Reenter new passphrase:
Note, that the master key encrypted with old keys and/or passphrase may
still exists in a metadata backup file.
Now when I boot, I enter the passphrase at the boot menu, a bunch of
stuff scrolls by, and then I see:
Enter passphrase for ada0s1d:
I enter the new passphrase and I see:
GEOM_ELI: Wrong key for ada0s1d. Tries left: 2.
Enter passphrase for ada0s1d:
I enter it again and I see:
GEOM_ELI: Wrong key for ada0s1d. Tries left: 1.
Enter passphrase for ada0s1d:
I enter the old passphrase and I see:
GEOM_ELI: Wrong key for ada0s1d. No tries left.
Mounting from zfs:zroot/ROOT/default failed with error 2.
I am then presented with some brief documentation and a prompt:
mountroot>
If I enter "?" to get a list of valid disk boot devices, I see:
List of GEOM managed disk devices:
ada0s1d ada0s1b ada0s1a ada0s1 ada0 cd0
I do not see ada0s1d.eli, which should be my decrypted root file system.
I have rebooted and tried more than once -- same result.
It would be useful to know why GELI for the root device is now broken,
and if it is possible to fix it (other than re-imaging/ re-installing).
What is the correct way to change the passphrase for FreeBSD 11.0
encrypted ZFS root?
Is this specific use-case documented anywhere?
David
