sorry Diane, this gave me extra motivation to try and do a better job and I reorganized things a bit more. Maybe you can have a look? it is your fault for the encouragement :)

@ldts Are we 100% sure this is true? We have clients that are using re-encryption and it picks up where it left off and does not block the boot in their case. Did something change here?

yes 100%.
I am not sure what configuration they might be running but in our case as soon as we enroll the TPM/PKCS11 tokens, we remove the passphrase and initiate the re-encryption.

If the volume is closed without having completed re-encryption, it just cant be opened again. It is easy to prototype locally on any machine (create a file of ~60MB, create an ext4 filesystem, and encrypt it with luks).

but tell me more about the configuration of those clients so I can see how they differ...

um, are you sure about what your clients are reporting??

see this:
https://github.com/foundriesio/meta-lmp/blob/main/meta-lmp-base/recipes-core/initrdscripts/initramfs-framework/cryptfs#L109

with the current code in the baseline, if online reencryption didnt finish and the board reboots we are going to block initramfs until it completes (resume is a blocking call)

having said that, this segment of code seems to succeed at opening ? which is kind of weird...
