I created a new partition(sda7) using cfdisk in Ubuntu 14.04. But, problem is that I don't able to set ext4 filesystem to the partition. When I go to type menu of the partition there is no ext4 partition option. Is there another name that is equivalent of ext4?

And when I tried to mount the sda7 sudo mount /dev/sda7 /mnt it shows--

mount: you must specify the filesystem type

But the output of fdisk -l shows all ext4 and Linux partitions as Linux and their ID is 83.

enter image description here

sda7->type

Entering sda7 type Now, how can I set this?

The file system used in a partition is “set” by creating the file system, not as the partition type in the partition table. Set the type to 83 (Linux), then create the file system:

mkfs.ext4 /dev/sda7

Then you’ll be able to mount it:

mount -t ext4 /dev/sda7 /mnt

  • I have done it. But, problem is that in /mnt directory threre is only one folder named lost+found and there is no increased space to put something. Commented Jun 7, 2017 at 5:34
  • The file system is empty, it’s up to you to create any directories you want. If you run df you should see available space on /mnt. Commented Jun 7, 2017 at 5:49
