rbd-replay-many  is  a  utility  for  replaying  a  rados block device (RBD) workload on several clients.
       Although all clients use the same workload, they replay against separate images.  This matches normal use
       of librbd, where each original client is a VM with its own image.

       Configuration and replay files are not automatically copied  to  clients.   Replay  images  must  already
       exist.

       Typical usage:

          rbd-replay-many host-0 host-1 --original-image=image -- -c ceph.conf replay.bin

       This results in the following commands being executed:

          ssh host-0 'rbd-replay' --map-image 'image=image-0' -c ceph.conf replay.bin
          ssh host-1 'rbd-replay' --map-image 'image=image-1' -c ceph.conf replay.bin

--original-imagename
              Specifies the name (and snap) of the originally traced image.  Necessary for correct name mapping.

       --image-prefixprefix
              Prefix  of  image  names  to  replay  against.   Specifying  --image-prefix=foo results in clients
              replaying against foo-0, foo-1, etc.  Defaults to the original image name.

       --execprogram
              Path to the rbd-replay executable.

       --delayseconds
              Delay between starting each client.  Defaults to 0.
