Defaults to \(aqrbd\(aq. .UNINDENT .INDENT 0.0 .TP .B \-\-latency\-multiplier Multiplies inter\-request latencies. Default: 1. .UNINDENT .INDENT 0.0 .TP .B \-\-read\-only Only replay non\-destructive requests. .UNINDENT .INDENT 0.0 .TP .B \-\-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. .UNINDENT .INDENT 0.0 .TP .B \-\-dump\-perf\-counters \fBExperimental\fP 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. .UNINDENT .SH EXAMPLES .sp To replay workload1 as fast as possible: .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C rbd\-replay \-\-latency\-multiplier=0 workload1 .ft P .fi .UNINDENT .UNINDENT .sp To replay workload1 but use test_image instead of prod_image: .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C rbd\-replay \-\-map\-image=prod_image=test_image workload1 .ft P .fi .UNINDENT .UNINDENT .SH AVAILABILITY .sp \fBrbd\-replay\fP is part of Ceph, a massively scalable, open-source, distributed storage system.
