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-investigation-and-guidance > You do not need to stop reading or writing objects to the bucket while resharding is happening. It would mean the dynamic resharding is online operation. However, it's not clear whether this feature blocks I/Os or not. Thanks, Satoru _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
