STEPS TO REPRODUCE

If I try to run luks_device against an already-open luks device named 'crypt00', I get a failure.

- name: Ensure encrypted disk is open
  community.crypto.luks_device:
    device: '/dev/sda'
    name: 'crypt00'
    state: 'opened'
    passphrase: "{{ luks_pw }}"

EXPECTED RESULTS

an "ok" response from ansible, indicating that the device is already open and no actions will be taken

ACTUAL RESULTS

I receive an error (listed below). If I change the name of the luks device to "enc00," the command works as expected. I suspect an issue similar to #409.

"luks_device error: Error while
 creating LUKS on /dev/sda: Cannot exclusively open /dev/sda, device in use.\

I tried to reproduce this in #821, but wasn't able to.

Can you provide the output of lsblk /dev/sda -nlo type,name and cryptsetup status crypt00 on your system?
