Hi there!

Digging deeper into Fly and really enjoying it! I did run into a hiccup trying to create a new Postgres cluster. Sorry if this is a dupe but couldn’t find a similar question on the forum or docs. I’m seeing this:

```bash
> flyctl postgres create
? App name: <intentionally blank>
? Select region: iad (Ashburn, Virginia (US))
? Select VM size: shared-cpu-1x - 256
? Volume size (GB): 10
Creating postgres cluster in organization <org>
Launching...⣯ Error Can't create volume, application is already using 1 of 1 zones in iad

```

Next, I tried a different region and the cluster deployed correctly. Odd! Not sure what “application is already using 1 of 1 zones in iad” means - I don’t have another app deployed in this region under the same organization.

Thanks!

That is a bug for sure, that happens when it can’t provision a new disk on a separate hardware stack. I just checked and it _should_ be working in iad, will you give it another try?

Absolutely, will give it a shot right now.

For future deployments, is it better for me to use `flyctrl postgres create` or provision from a new `fly init` of [GitHub - fly-apps/postgres-ha: Postgres + Stolon for HA clusters as Fly apps.](https://github.com/fly-apps/postgres-ha) ?

`flyctl postgres create` is better, but only because it hooks the cluster up so you can do things like `flyctl pg attach` to automatically connect apps to it. Otherwise, it’s the exact same thing.

Nice, yeah it’s super convenient.

Just tried another deployment to iad - looks like it’s working!

Thanks for these quick replies. I know this sort of support workload can be draining, but it gives me a lot of confidence to use fly over other providers.

No problem! It’s easy, really, we like talking in here.
