cryptsetup reencrypt --hash sha512 /dev/sdx
This works but it will re-encrypt the entire device.

Is it possible to re-encrypt a partition with the

command, to use the SHA-512 hash ?
Currently, my partition uses SHA-256, so I want to reencrypt without
losing any data. I have heard that the cryptsetup reencrypt does online
re-encryption, but the man page is not clear about how you can introduce a
new hash.
Is it even possible ?
