Hiya. Playing with a small cephs setup from the Quick start documentation.
Seeing an issue running rdb bench-write. Initial trace is provided
below, let me know if you need other information. fwiw the rados bench
works just fine.
Any idea what is causing this? Is it a parsing issue in the rbd command?
Thanks
