I was getting a Wordpress database connection error every other day. I created a 512 swap file (1GB droplet) and it made it about a week. I’m trying to increase the swap file 2GB. Here are the steps I took.
sudo swapoff /swapfile sudo dd if=/dev/zero of=swapfile bs=2048 count=1048576 sudo mkswap /swapfile
It reports: Setting up swapspace version 1, size = 1048572 KiB…
sudo swapon /swapfile
It looks like it only created a 1GB swapfile. When I use free-m it says 1023 for the swap. The file size via WinSCP is 2GB.
Is there a limit on the size of a swap file? If so, can I have two swap files? Or should I get a bigger droplet?

@nhatkhoa: <br> <br>“bs” stands for block size. So each “block” will be 2048 bytes. The Wikipedia article on the topic is pretty good: <br> <br>http://en.wikipedia.org/wiki/Dd_(Unix)#Block_size <br> <br>
