welcome to fdisk (util-linux 2.31.1).
changes will remain in memory only, until you decide to write them.
be careful before using the write command.

xxx@jxxx:~$ sudo mount /dev/mmcblk0p15 /home/xxx/node
ntfs signature is missing.
failed to mount '/dev/mmcblk0p15': invalid argument
the device '/dev/mmcblk0p15' doesn't seem to have a valid ntfs.
maybe the wrong device is used? or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? or the other way around?
