+**Partitions via fdisk**
+Ensure adequate unallocated space is available by adding more physical volumes
+or resizing in the case of virtual machines via something like below
+```
+qemu-img resize /path/to/image.qcow2 +size
+```
+where size can be +1G, +10G, +500M
+
+Run fdisk on your device `fdisk /dev/vda` and use the following core options to
+navigate
+| flag | Description |
+| p | lists all partitions currently on the device |
+| n | starts prompts to create new partition |
+| e | create extended partition applicable to mbr whose max is 4 primary|
+| t | redesignates a partition as something else e.g. swap|
+| L | while in t prompt lists all available labels you can apply to partition|
+| w | syncs/writes all changes to disk |
+
+
+`vim /etc/fstab` needs to be updated with the new partition information. You
+can append something like the following to it:
+```
+
+/dev/vda3   /storage    vfat    defaults 0 0
+/dev/vda5   none        swap    defaults 0 0
+
+```
+The first line will mount 3rd partition to `/storage` as a vfat partition. The
+second line will mount 5th partition as a swap. Mount point is none here.
+Make sure the mount points are created prior to force mounting like so
+
+```
+mkswap /dev/vda5   # writes metadata to /dev/vda5 as swap
+mount -a           # mounts everything in /etc/fstab
+swapon -a          # activates all partitions marked as swap for kernel to use
+findmnt --verify   # verifies /etc/fstab 
+```
