If you do not want to keep them around you would need to use --destroy
and use the lv path as input:
ceph-volume lvm zap --destroy osvg-sdd-db/2ukzAx-g9pZ-IyxU-Sp9h-fHv2-INNY-1vTpvz

In this case, you removed the LV so the wipefs failed because that LV
no longer exists. Do you have output on how it failed before?
