       rbd-replay - replay rados block device (RBD) workloads


       rbd-replay [ options ] replay_file


       rbd-replay is a utility for replaying rados block device (RBD) workloads.


       -c ceph.conf, --conf ceph.conf
              Use  ceph.conf  configuration  file  instead  of the default /etc/ceph/ceph.conf to
              determine monitor addresses during startup.

       -p pool, --pool pool
              Interact with the given pool.  Defaults to 'rbd'.

              Multiplies inter-request latencies.  Default: 1.

              Only replay non-destructive requests.

       --map-image rule
              Add a rule to map image names in the trace to image names in the replay cluster.  A
              rule of image1@snap1=image2@snap2 would map snap1 of image1 to snap2 of image2.

              Experimental  Dump  performance counters to standard out before an image is closed.
              Performance counters may be dumped multiple times if multiple images are closed, or
              if  the  same  image is opened and closed multiple times.  Performance counters and
              their meaning may change between versions.


       To replay workload1 as fast as possible:

          rbd-replay --latency-multiplier=0 workload1

       To replay workload1 but use test_image instead of prod_image:

          rbd-replay --map-image=prod_image=test_image workload1


       rbd-replay is part of Ceph, a massively scalable, open-source, distributed storage system.
       Please refer to the Ceph documentation at for more information.
