Hi,

I would like to ask about the procedure to retype a Cinder volume that is in-use (bootable volume, connected to a VM) from an encrypted (LUKS) type to a non-encrypted type (1000 IOPS). I tried to do this via the CLI[1], and while it seemed to work (at least according to the CLI output), the process didn’t complete successfully. Cinder logs[2] indicate that everything looks more or less fine: the volume is created, the volume migration is OK, and the retype is marked as completed. However, in the end, it doesn’t work (final output of [1]).

I reviewed the blueprint at https://blueprints.launchpad.net/cinder/+spec/retype-encrypted-volume, which appears to be implemented. Am I doing something wrong, or does this functionality not work as expected?

Thanks in advance for your help and guidance.
