Aux function to replace PV with specifically damaged device. Usage: aux error_dev "$dev1" 8:32 96:8 Replaces from 8 sector 32 error 512b sectors and from 96 sector next 8 sectors will fail on rw. Rest of device is preserved. For testing: dd if="$dev1" of=x bs=512 count=104 conv=sync,noerror iflag=direct
