Fly Postgres VM Replica down after scale down

[markoskt]

Hello.

I tried to scale down my Postgres cluster using the command below

fly machine update 5683d470b33498 --vm-cpus 1

And the replica health check didn’t pass and now it’s down.

Can someone help me figure out what happened?

Thank you

I had previously been working with Marco on something else, so I sent him an email earlier, but now, should Marco or anyone else run into this problem in the future, a better solution will be to use fly pg renew-certs, which has been implemented in flyctl since 05-29-2024. Run fly pg renew-certs, then do a new fly deploy, then you should be able to update your machine.
