almost 15x faster, we gotta do this, it'll speed up the CI tremendously.

FTR, right now it takes around 12 minutes for cephadm to deploy a cluster, potentially maybe at the speedups we see above it can go down to a few minutes (like it was before?) and the HA is taking almost 50 minutes should be cut down significnatly.

Hello @mnaser X stray daemon(s) not managed by cephadm We are having this on our sandbox env, do you have any insights about it? We know the issue/bug is superficial and it looks like a bug

Hello @mnaser

X stray daemon(s) not managed by cephadm

We are having this on our sandbox env, do you have any insights about it?

We know the issue/bug is superficial and it looks like a bug

This is not a bug but a result of how things run inside Atmosphere.

Do you have an open issue about it? or a way to solve this?

It's not a bug so there's no point in solving this. It's silenced by our deployment tooling.

Please let's keep this issue on topic.

Thanks
