Description

luminous v12.1.1

With rgw_dynamic_resharding=true about 10% of buckets` indexes were resharded each to 65521 shards.
Buckets contained 200-400 objects or less.

After disabling dynamic resharding after 2 days of test running anyway one bucket index was resharded, also to 65521 shards.
