+---
+This post will set out to explain how you can increase the disk size of a virtual disk inside a VM after increasing its size in your hypervisor.
+It does assume some familiarity with Linux and partitioning.
+
+Its is mainly aimed at [CentOS](#centos) and [Debian](#debian). Though this should also be relevant if you are using the same disk technologies.
+Those being LVM+XFS for the CentOS and plain ext4 for Debian.
+
+# CentOS
+This assumes a fairly standard CentOS install that uses LVM and XFS.
+
+## TL;DR
+```shell
+sudo cfdisk
+sudo pvresize /dev/sda3
+sudo lvextend -l 100%FREE /dev/mapper/cl-root
+sudo xfs_growfs /
+```
+
+## Step 0: Hypervisor
+Before doing this make sure you have expanded the disk to the desired size in your hypervisor of choice (eg. within proxmox).
+
+## Step 1: Increase partition
+Now increase the size of the root partition using something like `fdisk` or `cfdisk`. If your root partition is not the last partition this would also entail removing and re-creating your swap partition, for information on how to do that I'll refer to the [arch wiki][swap].
+
+## Step 2: Resize Physical Volume
+Now that the partition is expanded you should expand the accompanying LVM Physical Volume as follows:
+```shell
+pvresize /dev/sda3
+```
+Where `/dev/sda3` is the partition you expanded in [step 1](#step-1).
+
+For more information on `pvresize` see its [man page][pvresize]
+
+## Step 3: Extend Logical Volume 
+Now that the PV has been resized you can resize the LVM Logical Volume with `lvextend` like so:
+```shell
+lvextend -l 100%FREE /dev/mapper/cl-root
+```
+In this command the `100%FREE` refers to all remaing space of the PV and the `/dev/mapper/cl-root` should be the location of your root volume; which you can check with `lsblk` if uncertain.
+
+Again you can check its [man page][lvextend] for any more information.
+
+## Step 4: Grow XFS
+Finally we need to expand the actual XFS filesystem, this is fairly easy luckily:
+```shell
+xfs_growfs /
+```
+`xfs_growfs` takes the mountpoint of the filesystem as its argument, which is `/` in this case.
+
+# Debian
+This assumes a fairly standard Debian install that uses ext4.
+
+## TL;DR
+```shell
+sudo cfdisk
+sudo pvresize /dev/sda3
+sudo lvextend -l 100%FREE /dev/mapper/cl-root
+sudo xfs_growfs /
+```
+
+## Step 0: Hypervisor
+Before doing this make sure you have expanded the disk to the desired size in your hypervisor of choice (eg. within proxmox).
+
+## Step 1: Recreate Partitions
+Now increase the size of the root partition using something like `fdisk` or `cfdisk`.
+Debian uses something called "Extended Partitions" by default which makes this a bit more difficult. Instead of simply resizing the partition you need to:
+1. Note down the starting sector of the extended partition
+2. Remove the extended partion
+3. Recreate the extended partition now using full available size
+4. Recreate the root partition
+
+If you have any swap in the extended partition or after it you would need to recreate this as well. Some information with regards to swap can be found on the [arch wiki][swap].
+
+## Step 2: Partprobe
+Now we need to use `partprobe` the disk to make debian aware of the size change.
+This is simply just doing:
+```shell
+sudo partprobe /dev/sda
+```
+where `/dev/sda` is your expanded partion.
+
+## Step 3: Resize filesystem
+Finally you can resize the actual filesystem with `resize2fs` like so:
+```shell
+sudo resize2fs /dev/sda5
+```
+where `/dev/sda5` is the partition mounted as root.
+
+# Appendix
+Some useful notes that aren't necessarily part of the rest of this how-to.
+
+## LVM Debugging
+If LVM for some reason does not like to behave these commands may come in useful:
+
+**Listing all Logical Volumes**\
+[`lvs`]
+
+**Getting information about a specific Physical Volume**\
+[`pvdisplay /dev/sda2 -m`][`pvdisplay`]
