.nf
\fBrbd\-replay\fP [ \fIoptions\fP ] \fIreplay_file\fP
.fi
.sp
.SH DESCRIPTION
.sp
\fBrbd\-replay\fP is a utility for replaying rados block device (RBD) workloads.
.SH OPTIONS
.INDENT 0.0
.TP
.B \-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.
.UNINDENT
.INDENT 0.0
.TP
.B \-p pool, \-\-pool pool
Interact with the given pool.  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
.SH EXAMPLES
.sp
To replay workload1 as fast as possible:

.sp
.nf
.ft C
rbd\-replay \-\-latency\-multiplier=0 workload1
.ft P
.fi
.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
