Increase Swap size of server

 

1. First disable the swap and delete it

    sudo swapoff /swapfile  
    sudo rm  /swapfile
   

2. Create new swap space of size 16 GB (16 * 1024 = 16384). bs is the block size. Basically bs * count = bytes to be allocated (in this case 16 GB). Here bs = 1M (M stands for mega, so we are assigning 1MB block size) and we are allocating 16384 * 1MB (=16GB) to swap.

    sudo dd if=/dev/zero of=/swapfile bs=1M count=16384
   

3. Give it the read/write permission for root

    sudo chmod 600 /swapfile
   

4. Format it to swap

    sudo mkswap /swapfile
   

5. Turn on swap again

    sudo swapon /swapfile
   

6. Now reboot the PC for the above changes to take place.
