My laptop contains an 512gb ssd of which i have made 3 partitions. The C drive has windows os installed, the d drive has my files and the other drive is where ubuntu 18.04 is installed. Every time i try to mount it it shows " can't find in /etc/fstab". I tried
sudo mkdir -p /mnt/Dvol
sudo mount /dev/nvme0n1p4 /mnt/Dvol
