I'd already looked at those. lvremove takes an LV identifier as argument, but since the cloned partition has the same id as the original, and the original is still in use on the active system, it won't let me remove it: $ sudo lvremove -t -f fedora_localhost-live/swap TEST MODE: Metadata will NOT be updated and volumes will not be (de)activated. /dev/sde: open failed: No medium found <------------------ I don't know what this is ------------- WARNING: Not using device /dev/sdc3 for PV VKT04D-m4CK-6n7L-vSMI-vohC-W8bt-zPVCxS.
