Before we resize primary partition, let us list the available partitions. Re-verify the new size of root partition to make sure our steps to extend non lvm root partition was successful.

How to expand partition with examples in Linux. Partition information is stored in a partition table. It seems kind of strange to use cfdisk to view the partition table, then use fdisk to do the work when you could just do it in cfdisk, and a bit more user friendly at that. Apart from that we don’t want to restart servers. Your email address will not be published. Ouch! Here my VM is installed on /dev/sda device where /dev/sda1 is boot partition, /dev/sda2 is root while /dev/sda3 is for swap.. Additionally I have left some unallocated free space in /dev/sda for the demonstration of this article to extend non lvm root partition. Let’s start with running the following command: This will make the terminal enter in fdisk mode: once there, type This will trigger the on-line resizing of the file system, which will be extended in order to use all the available logical volume space. Currently my swap partition is enabled and is the last partition of /dev/sda. So we must first delete swap partition here before we change size of partition as we need root to be the last partition in /dev/sda, So we will turn off the swap partition before we disable it, Now it is time to use fdisk utility to resize partition. For the record, prepend commands with “sudo” means typing “sudo fdisk /dev/sda” instead of “fdisk /dev/sda”, and so on.

This will not impact the content of root partition and only partition table is modified. After deleting swap, root partition will become the last partition on /dev/sda after which we can resize primary partition. This article assumes you're using either a GPT partition table, or an msdos partition table using primary partition types to extend non lvm root partition. Right after that, type n to create a brand-new second partition: choose the same partition mode of the previous one (that would be Primary in the above scenario), then input the START numeric value you’ve recorded earlier – which shoud be the suggested default; also, make sure that the end is at the end of the disk – which should also be the default. Note down the start sector of the root partition before you expand partition. Here’s a great tutorial for that: Be careful before using the write command.

very appreciated for the the detail instruction! I hope that this post will help more System Administrators in working with their Linux systems.

Thanks for the straight forward approach to adding disk drive space. – To create more than four partitions, one of these four partitions can be divided into many smaller partitions, called logical partitions. To do this, you will need to use the "rm" command within parted. mount: wrong fs type option, bad superblock on /dev/sda2 missing codepage.
