luks_device state=absent no longer works on some RHEL 7.9 VMs in CI

[felixfontein]

SUMMARY

The problem seems to be that wipefs --all doesn't modify the LUKS header enough that cryptsetup isLuks determines that this is no longer a LUKS device.

Interestingly, this only happens with ansible-core's devel branch (not with older ones on RHEL 7.9), and it doesn't happen on RHEL 7.8 or RHEL 8.4.

I'm a bit lost on what to do (and don't have enough time to try to analyze this further right now). If anyone has some more ideas, I'd be happy to hear :)

luks_device

I guess it's better to use cryptsetup luksErase instead of wipefs for this.
