Benchmarking the Ceph Block Device

The tools, rados bench, and RADOS load-gen, which we discussed in the last recipe, are used to benchmark the Ceph cluster pool.

  1. Create a Ceph Block Device named block-device1, of size 10 G, and map it:
        # rbd create block-device1 --size 10240 --image-feature layering
# rbd info --image block-device1...
