	"Keys must be loaded for encryption root of '%s' (%s)."),
	zfs_get_name(zhp), prop_encroot);

you need to load-key on rpool itself, not child dataset.

Offtopic, but it's not the best practice to use root dataset (rpool itself) for anything, next time it's better to encrypt at least at rpool/ROOT level.

Hello I tried, and they gave me this error

'Key load error: Failed to open key material file: No such file or directory'
That is what I get

It looks like your key location is a file and the file doesn't exist on this system. You should try to find the key and may be change the key location property.

My question is how to do ? How to find the file?
How to find a key ?

I've tried everything I know, and isn't working

What does the zfs list -o name,encryption,encryptionroot,keylocation,keyformat -r rpool say?
