Description of problem: This happened during an LVM pvmove that was moving all logical volumes from one physical disk to an other. I had similar problems while attempting the same pvmove ~1 month ago (https://retrace.fedoraproject.org/faf/reports/1100937/, https://retrace.fedoraproject.org/faf/reports/1100945/, https://retrace.fedoraproject.org/faf/reports/1101944/).
