# Add Swap Space To System

We can add swap space to the system by following method -

## Check for existing swap space

```bash
sudo swapon --show
```

## Create a new swap space

```bash
sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
```

## Enable swap space

```bash
sudo mkswap /swapfile
sudo swapon /swapfile
```

## Verify that the swap space exists

```bash
sudo swapon --show
```

## Make swap persistent upon restart

```bash
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
```
