How to mount Linux logical partition (ubuntu/debian)?

Question

linux

Hello, I have a server with a /dev/sda3 root partition. Through fdisk /dev/sda3 I created an extended (logical) partition /dev/sda3/sda3p1. Can I somehow mount it and how do I work with it? The goal is to create a partition for GlusterFS without formatting the main partition (that's why I thought that a logical one would do).

Answer 1

mount /dev/sda3p1 /path/to/mp
