[ceph-users] Does dynamic resharding block I/Os by design?

Hi, I have a Ceph cluster used for RGW and RBD. I found that all I/Os to RGW seemed to be blocked while dynamic resharding. Could you tell me whether this behavior is by design or not? I attached a graph which means I/O seemed to be blocked. Here x-axis is time and y-axis is the number of RADOS objects. In addition, dynamic resharding was run between 16:22:30 and 16:31:30. I read the official documents about dynamic resharding. But there is no description about blocking during dynamic resharding. https://docs.ceph.com/en/octopus/radosgw/dynamicresharding/ In addition, I read the following Red Hat's blog post. https://www.redhat.com/ja/blog/ceph-rgw-dynamic-bucket-sharding-performance… It would mean the dynamic resharding is online operation. However, it's not clear whether this feature blocks I/Os or not. Thanks, Satoru
