Hi everyone, I am facing an issue with bucket resharding. It started with a warning on my ceph cluster health : [root@ceph_monitor01 ~]# ceph -s cluster: id: 2da0734-2521-1p7r-8b4c-4a265219e807 health: HEALTH_WARN 1 large omap objects Finds out I had a problem with a bucket : "buckets": [ { "bucket": "bucket-elementary-1", "tenant": "", "num_objects": 615915, "num_shards": 3, "objects_per_shard": 205305, "fill_status": "OVER 100.000000%" }, I was wondering why the dynamic sharding wasn't doing its job but find out it was in the sharding queue : [root@ceph_monitor01 ~]# radosgw-admin reshard list [ { "time": "2020-05-14 09:42:10.905080Z", "tenant": "", "bucket_name": " bucket-elementary-1", "bucket_id": "97c1cfac-009f-4f7d-8d9d-9097c322c606.51988974.133", "new_instance_id": "", "old_num_shards": 3, "new_num_shards": 12 } ] As i wanted to process on taks in this queue I tried to run : radosgw-admin reshard process But turns out in an error : [root@ceph_monitor01 ~]# radosgw-admin reshard process ERROR: failed to process reshard logs, error=(22) Invalid argument 2020-05-14 14:15:10.225362 7f99b0437dc0 0 RGWReshardLock::lock failed to acquire lock on bucket-college-35:97c1cfac-009f-4f7d-8d9d-9097c322c606.51988974.133 ret=-22 2020-05-14 14:15:10.225376 7f99b0437dc0 0 process_single_logshardERROR in reshard_bucket bucket-elementary-1:(22) Invalid argument Tried to cancel it tu do it manually but had the same error [root@ceph_monitor01 ~]# radosgw-admin reshard cancel --bucket bucket-elementary-1 Error canceling bucket bucket-elementary-1 resharding: (22) Invalid argument 2020-05-14 14:16:42.196023 7fa0b1655dc0 0 RGWReshardLock::lock failed to acquire lock on bucket-elementary-1:97c1cfac-009f-4f7d-8d9d-9097c322c606.51988974.133 ret=-22 I found this post searching for an answer : https://tracker.ceph.com/issues/39970 But it seems that it will not help me since my whole cluster (monitors / data nodes / rgw) is on : [root@ceph_monitor01 ~]# ceph --version ceph version 12.2.13 (584a20eb0237c657dc0567da126be145106aa47e) luminous (stable) This is what I have on the status of this bucket : [root@ceph_monitor01 ~]# radosgw-admin reshard status --bucket= bucket-elementary-1 [ { "reshard_status": "CLS_RGW_RESHARD_NONE", "new_bucket_instance_id": "", "num_shards": 18446744073709551615 }, { "reshard_status": "CLS_RGW_RESHARD_NONE", "new_bucket_instance_id": "", "num_shards": 18446744073709551615 }, { "reshard_status": "CLS_RGW_RESHARD_NONE", "new_bucket_instance_id": "", "num_shards": 18446744073709551615 } ] Any help would be appreciated.
