Description David Teigland 2022-06-09 19:16:38 UTC 
Description of problem:

lvmdevices --deldev would not work when the name device was missing.

This seems to have been fixed as part of rhel9 bug 2040482, but that bug is a confusing combination of issues and fixes, so creating a new bug to backport this specific fix to rhel8.

fix in main branch:
