/dev/mapper/control: open failed: Permission denied
Failure to communicate with kernel device-mapper driver.
Incompatible libdevmapper � and kernel driver
usage : kpartx [-a|-d|-l] [-f] [-v] wholedisk
        -a add partition devmappings
        -r devmappings will be readonly
        -d del partition devmappings
        -u update partition devmappings
        -l list partitions devmappings that would be added by -a
        -p set device name-partition number delimiter
        -g force GUID partition table (GPT)
        -f force devmap create
        -v verbose
        -s sync mode. Don't return until the partitions are created


kpartx expects a block device as an argument.
