Casey,
Thanks.
I picked a few buckets in question and they have not been resharded (num_shards not changed since creation). However, radosgw-admin lc reshard fix --bucket BUCKET did restore the lifecycle and radosgw-admin lc process --bucket BUCKETNAME did start deleting tihngs as expected on the slave side,
I will check one I did did not process by hand to see if it has run tomorrow. I think may still have to change
rgw_lc_max_workerrgw_lc_max_wp_workerrgw_lifecycle_work_time
but we will see.

hi Chris,
https://docs.ceph.com/en/latest/radosgw/dynamicresharding/#lifecycle-fixes
may be relevant here. there's a `radosgw-admin lc reshard fix` command
that you can run on the secondary site to add buckets back to the lc
list. if you omit the --bucket argument, it should scan all buckets
and re-link everything with a lifecycle policy

I recently discovered (about a month after the el9 and reef 18.2.4 updates) that lifecycle expiration was (mostly) not working on the secondary zone side.I had thought initially that there may be replication issues, but while there are replication issues on individual buckets that required me to full sync individual buckets, the majority of the issues are becauselifecycle expiration is not working on the secondary side.
