when i delete snapshot of volume, it has log

2019-03-29 15:03:21.391 7f1cf37fe700 -1 librbd::SnapshotUnprotectRequest: cannot get children for pool '.rgw.root'

I don't create .rgw.root and default.rgw.meta pool and not create new radosgw.

why my cluster auto create rgw pool ? How i can prevent this issue.

Thanks.

Please reference the following [1] when creating your CephX user caps. Specifically, your user is required to have read permission on every pool for at least the "rbd_children" object.
