RBD-REPLAY(8)			     Ceph			 RBD-REPLAY(8)

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

SYNOPSIS
       rbd-replay [ options ] replay_file

DESCRIPTION
       rbd-replay  is  a  utility for replaying	rados block device (RBD) work-
       loads.

OPTIONS
       -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'.

       --latency-multiplier
	      Multiplies inter-request latencies.  Default: 1.

       --read-only
	      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.

       --dump-perf-counters
	      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.

EXAMPLES
       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
