Usage: /usr/bin/rbd-replay --conf=<config_file> <replay_file>
Options:
-p, --pool-name <pool> Name of the pool to use. Default: rbd
--latency-multiplier <float> Multiplies inter-request latencies. Default: 1
--read-only Only perform non-destructive operations.
--map-image <rule> Add a rule to map image names in the trace to
image names in the replay cluster.
--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.
Image mapping rules:
A rule of image1@snap1=image2@snap2 would map snap1 of image1 to snap2 of
image2.

Examples (2) from the manual page, untested
rbd-replay --latency-multiplier=0 workload1
To replay workload1 as fast as possible:rbd-replay --map-image=prod_image=test_image workload1
To replay workload1 but use test_image instead of prod_image:
