RGW Squid radosgw-admin lc process not working

[Adam Prycki <aprycki@xxxxxxxxxxxxx>]

Hello,

this weekend I was trying to test if squid still suffers from orphaned 
objects from multipart uploads.
https://tracker.ceph.com/issues/44660

I've previously encountered major issues with orphaned objects when 
using lifecycle transitions and server side copies. Especially on slower 
clusters.

So far I couldn't induce orphaned objects during upload and server side 
copy :D

I couldn't quickly test lifecycle transition because I cannot get 
`radosgw-admin lc process` to work on any bucket.

I'm using 19.2.0 cephadm cluster with fresh rgw pools (I've removed all 
rgw and created a fresh instnace)


Lifecycle config is very simple and based on aws example:

<LifecycleConfiguration>
  <Rule>
    <ID>transition</ID>
    <Filter>
      <Prefix></Prefix>
    </Filter>
    <Status>Enabled</Status>
    <Transition>
      <Days>0</Days>
      <StorageClass>STANDARD_IA</StorageClass>
    </Transition>
  </Rule>
</LifecycleConfiguration>

I have STANDARD and STANDARD_IA storage classes in my placement. I'm 
testing on a bucket with 2 objects, one on STANDARD and one on STANDARD_IA.
[
  {
    "key": "default-placement",
    "val": {
      "index_pool": "n8.rgw.buckets.default-placement.index",
      "storage_classes": {
        "STANDARD": {
          "data_pool": "n8.rgw.buckets.default-placement.data.STANDARD"
        },
        "STANDARD_IA": {
          "data_pool": "n8.rgw.buckets.default-placement.data.STANDARD_IA"
        }
      },
      "data_extra_pool": "n8.rgw.buckets.default-placement.non-ec",
      "index_type": 0,
      "inline_data": true
    }
  }
]

running `radosgw-admin lc process` results in this error
lifecycle: RGWLC::process() head.marker !empty() at START for shard==lc.14

running `radosgw-admin lc process --bucket test1` results in no output

ceph claims that lifecycle executed but no data was copied between pools

radosgw-admin lc list
[
    {
        "bucket": ":test1:a0f7b0da-04a7-4053-b710-a15897233e86.334949.1",
        "shard": "lc.14",
        "started": "Sun, 02 Feb 2025 22:45:37 GMT",
        "status": "COMPLETE"
    }
]

I've looked on ceph issue tracker but couldn't find anyone mentioning 
similar lifecycle issues on Squid. (My test buckets are not versioned.)

Is this a bug or some kind of misconfiguration?


Best regards
