How do I create and mount a new ext4 filesystem? First, make sure that you have e2fsprogs 1.41.0 or later installed on your system. This is required for ext4 support. If the new partition where you would like to create the ext4 filesystem is /dev/sdb1, then all you have to type is: /sbin/mke2fs -t ext4 /dev/sdb1 Then to mount this new filesystem, all you need to do is: mkdir /mnt/test mount -t ext4 /dev/sdb1 /mnt/test .
