Hello you all.
Im trying to understand the billing and pricing.
Read the prices and deployed my first app on fly-io.
Now when I’m looking at the billing, I cant figure out what generates the cost.
Example;
717 GB/hr × Volume: SSD Storage (at $0.0002083333 / month) $0.15
If someone could explain this to me, I would get much more comfortable on predicting actual cost =D
Thanks in advance
Hi @drobban
You pay for storage per hour per gigabyte provisioned.
So you could have had one 1GB volume provisioned for 717 hours, or one 3GB volume provisioned for 239 hours, or even three 1GB volumes provisioned for 239 hours.
Thank you for the answer. Where can I find information about my storage usage?
In regards to billing, whatever it says on your bill is pretty much all the information there is, though fly.io support might be able to give you more information regarding something specific.
If you want to see what volumes are currently provisioned for your app you can use the fly volumes list command. Here are the docs flyctl volumes · Fly Docs
Again thank you.
Just trying to figure out what generates the costs. As is, it appears to black be magic as I dont have any fly volumes attached
Hi @drobban I can see that you have two 10GB volumes for your database app. If that was a mistake and you wanted a lower size here’s how another user solved it:
Let me know if we can help more 
sounds weird. as I just used the automated tool for launching a phoenix app…
Must have screwed something up
Thanks for the help
I assume this is a problem
Not sure how Im supposed to be able to remove a volume that isnt visible to me?
Volumes are per-app. I think since you’re on your Elixir app and you don’t have volumes there you’d see this empty list.
Try this:
fly volumes list -a YOUR_DATABASE_APP_NAME
Thank you!
The instructions worked very well. As a new user to this platform I’m not sure whats normal;

Is it normal for the app to start spitting out the above warning?
Not sure if it did before I started changing stuff.
Oh, that sounds very weird. Can I ask how did you get to this bug?
I assume I did something stupid, here is a cleaned up log;

The warning is then spit out into the logs

Should perhaps add that everything works just fine. Seems just little odd to get warnings spammed into the logs I dont know the cause for.
Everything might be okay, I can see here that your DB has all passed health checks. Do let us know if anything happens
