Re: How to remove remaining bucket index shard objects

Hi,

What you mean "strange"? It is normal, the object need only for OMAP data, not for actual data. Is only key for k,v database
I see that you have lower number of objects, some of your PG don't have data at all. I suggest check your buckets for properly resharding process

How this look (the index pool) usually:

```
[root@ceph-mon0 tools]# ./show_osd_pool_pg_usage.sh default.rgw.buckets.index
id     used_mbytes  used_objects  omap_used_mbytes    omap_used_keys
