I wanted to encrypt against physical theft but then I realized that the server weighs 20kg and there’s more valuable and lighter stuff to steal. And a thief would never be able to mount the zfs array, they’ll just fence my $2000 server for $50 and someone else will sell it piece by piece on ebay. And between people who buys used drives online on ebay almost nobody is going to do a full surface scan of a 12tb drive in the hopes of finding valuable data.
