This might not be a Ceph issue at all depending on if you're using any sort of caching. If you have caching on your disk controllers at all, then the write might have happened to the cache but never made it to the OSD disks which would show up as problems on the VM RBDs. Make sure you have proper BBU's on your disk controllers and/or disable caching that might be enabled on your controllers or disks that could be benefiting you with write speed while the cluster is healthy, but potentially causing you to run into this state during a catastrophe.
