Ceph show health ok on gui and cli.

Thanks.

This looks like a snapshot has no parent anymore. Try to find which snapshot the message belongs to, by looking through the rbd info of the images/snapshots and look for the 'rbd_data.3230f2ae8944a', as it marks the prefix for each object written to ceph.
