Hi, We have an old cluster with 3 nodes running ceph version 15.2.17. We have a PG in state active+clean+inconsistent which we are unable to repair. It's an RBD pool in use by kubernetes. The earliest indication of the issue comes from ceph-osd.4.log on one of the nodes: *2024-05-23T14:34:38.003+0200 7f00b907c700 0 log_channel(cluster) log [DBG] : 20.4 repair
