**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
|
||
|
|
```
|
||
