How to change swap priority?

To change the swap priority of a swap device in Linux, follow these steps:

Identify Current Swap Devices: Check your current swap devices and their priorities using:
```
swapon --show
```
Turn Off the Swap Device: If the swap device is currently active, you need to turn it off:
```
sudo swapoff /dev/sdX
```
Replace /dev/sdX with the actual swap device (e.g., /dev/sda2).
Turn On the Swap Device with New Priority: Use the swapon command to turn it back on with the desired priority:
```
sudo swapon -p <new_priority> /dev/sdX
```
Replace <new_priority> with the desired priority value and /dev/sdX with your swap device.
Verify the Changes: Check the swap priorities again to confirm the change:
```
swapon --show
```

To change the priority of /dev/sda2 to 10:

sudo swapoff /dev/sda2
sudo swapon -p 10 /dev/sda2
