Re: cgd on dk on 4k block size disk (Thomas Klausner) writes:

That's the "virtual" disk geometry presented by cgd. 512 is also
the block sized used for encryption.

No. The underlying disk only accepts 4k aligned I/O (i.e. its physical
blocks). cgd needs to adopt the underlying disks block size, it should
already handle splitting the crypto operations to 512 byte units.
