 BMG | Mic92: I pushed an updated version of the dangling refs parquet file which you should be able to run through simple gc to remove them just like with nixos images.
I also locally tweaked the dangling refs script to load those first order dangling refs into the deletion set and the result was no more dangling refs found:
==================================================
SUMMARY
==================================================
Entries with dangling refs: 0
No dangling references found
| 16:55:49 |
| BMG | So removing the nixos images and the extra dangling refs results in store paths with missing references due to the removals | 16:56:26 |
| BMG | * So removing the nixos images and the extra dangling refs results in no store paths with missing references due to the removals | 16:56:35 |
| BMG | So to be clear, narinfos-nixos-images-2026-01-06T01-13Z.parquet is the proposed deletion, narinfos-nixos-images-dangling-refs-2026-01-06T01-13Z.parquet is anything that referred to the entries in the first file. | 16:57:45 |
| BMG | I'm gonna test with a dry run to be sure there's no issues with the dangling refs format | 16:59:07 |
| BMG | Had to fix a schema issue, pushed an update to the dataset and just tested it with a dry run:
{
"dry_run": true,
"targets": {
"nar_infos": 105944
},
"removed": {
"nars": 105944,
"nar_infos": 105944,
"errors": 0
},
"missing_in_s3": {
"nars": 0,
"nar_infos": 0
}
}

 Arian | If you are nervous about correctness we could enable bucket versioning + a Lifecycle rule that moves deleted objects into glacier | 08:30:17 |
| Arian | ```
{
"Rules": [
{
"Id": "archive-deleted-objects",
"Status": "Enabled",
"NoncurrentVersionTransitions": [
{
"NoncurrentDays": 0,
"StorageClass": "GLACIER_IR"
}
]
}
]
}``` | 08:30:25 |
| Arian | @joerg:thalheim.io are you still in Brussels today or tomorrow? | 08:31:22 |
 Mic92 | Arian: I am. | 08:56:48 |
| Mic92 | I am on the guix days. Maybe we can meet in the Numtide venue in the evening? | 08:57:25 |
| Mic92 | * I am on the guix days the next two days. Maybe we can meet in the Numtide venue in the evening? | 08:57:34 |
| Mic92 | I actually wanted to ask regarding the bucket versioning, because the implications are a bit unclear to me yet. | 08:58:04 |
| Mic92 | okay, we might than actually want to remotve the dangling refs dataset before we run the nixos images one. | 09:00:44 |
| Mic92 | * Arian: I am. I will leave on Wednesday | 09:00:50 |

| Corngood | I've got a couple of build failures due to free space that I'd like to restart:
https://hydra.nixos.org/build/320776458
https://hydra.nixos.org/build/320776631
Is this the right place to ask about that? | 00:28:53 |
 hexa (signing key rotation when) | restarted | 00:37:11 |
| Corngood | Thanks. Those particular builds are now showing as passed, but if I look at a build like https://hydra.nixos.org/build/320776594, it shows a propagated failure from one of those previously failing builds, and it doesn't look like it's queued. Is there anything I need to do about those, or will they sort themselves out? | 14:32:54 |
 vcunat | Unfortunately there are two other options I know about
- restart each of these manually
- restart completely all non-succeeding jobs in an eval
| 14:40:24 |

 K900 | Oh balls | 07:52:20 |
| K900 | It's hardcoded in nix-index too | 07:53:03 |
| K900 | Oh wait no it's not | 07:53:58 |
