Cardano-node: [BUG] - Rewards are missing

[peteremiljensen]

Summary
Hi. We're operating the following three pools:

| | |
|------|------|
| ETO1 | a3e71398e80739522e907c35b8f652064e5268e62e9b78a9603f6b98 |
| ETO2 | 2bf5a031b46b34c07937a769ff6f82b6a78a25c71022eaaf1f20eec9 |
| ETO3 | 32fdb90d73865d16463fe1e092c7814a9f035f781a661d9d43ed7443 |

From their inceptions to epoch 227 they all shared the same owner and reward address (6877dcb866858b2a4941351c98cd67202262bfd82a016cbbaa073927). This resulted in only receiving rewards from one of the pools and not all three of them. As we assumed something was wrong: We updated the pools so they all have their own reward/owner wallet. Epoch 227 is the first epoch with the update, and we've just received the rewards from that epoch; resulting in three times the amount than before.

I hope it makes sense.

Steps to reproduce
Steps to reproduce the behavior:

1. Create three pools with the same owner and rewards stake key
2. Wait until rewards are distributed
3. Observe that only one of the pools gives rewards
4. Now update 2 of the pools with their own owner and rewards stake key
5. Observe that you now receive rewards for all of them

Expected behavior
I would expect rewards from all three pools to be accumulated, instead of rewards from just one of them being distributed.

System info:

• OS: Ubuntu
• Version: 20.04
• Node version: 1.20.0

Could you clarify what is the unexpected part here?
One wallet is not supposed to be pledging/owning against multiple pools, if that's what you're really thinking.
Your step 1-3 sounded like a mistake on your end, you corrected your setup using step 4 and confirm that it works at step 5.
You cannot pledge from same owner to 3 different pools at once - that is, and should be, the expected behaviour.

Okay. I've now executed a test in a private network with 2 pools. The pools are sharing the same rewards address but different owner addresses. I'm still only receiving rewards from one of the pools. As soon as they don't share the rewards address the total received amount of the rewards are doubled. As I view it, it's not related to pledging.

I would expect multiple pools sharing the same rewards address to receive the rewards from all pools. This is how it worked in ITN.

Maybe I'm doing or expecting something wrong?

Thank you very much

The following is an excerpt of the rewards paid out in each epoch:

| EPOCH | Reward Addr 1 | Reward Addr 2 | Shared Reward Addr | Total |
|-------|----------------|----------------|--------------------|----------------|
| 49 | 138,626.984079 | 169,432.980541 | | 308,059.96462 |
| 50 | 184,590.545244 | 129,897.050357 | | 314,487.595601 |
| 51 | 154,289.581026 | 130,552.722407 | | 284,842.303433 |
| 52 | 132,709.780181 | 127,605.557866 | | 260,315.338047 |
| 53 | 127,830.915687 | 58,589.169690 | | 186,420.085377 |
| 54 | 110,376.044306 | 115,393.137229 | | 225,769.181535 |
| 55 | | | 88,703.594680 | 88,703.594680 |
| 56 | | | 98,249.913365 | 98,249.913365 |
| 57 | | | 77,922.059291 | 77,922.059291 |
| 58 | | | 68,425.228861 | 68,425.228861 |
| 59 | | | 69,809.739657 | 69,809.739657 |
| 60 | | | 70,167.997113 | 70,167.997113 |
| 61 | | | 70,415.875564 | 70,415.875564 |

As you can see there is a large jump at epoch 55. This is the epoch where the pools now share the same reward address.

Here is the genesis file used to generate this test: https://gist.github.com/peteremiljensen/ef169e7bc257cb142e93628c36bd237b

After Epoch 62, I shutdown pool 1. Now, no new rewards were paid to the shared rewards address. You would think that pool 2 would still contribute.

i can confirm this, learned it the hard way last epoch on the mainnet. from the protocol standpoint it should be no issue, but i also got only rewards from one pool into the rewards-account instead of from two pools.
