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. .sp Configuration and replay files are not automatically copied to clients. Replay images must already exist. .SH OPTIONS .INDENT 0.0 .TP .B \-\-original\-image name Specifies the name (and snap) of the originally traced image. Necessary for correct name mapping. .UNINDENT .INDENT 0.0 .TP .B \-\-image\-prefix prefix 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. .UNINDENT .INDENT 0.0 .TP .B \-\-exec program Path to the rbd\-replay executable. .UNINDENT .INDENT 0.0 .TP .B \-\-delay seconds Delay between starting each client. Defaults to 0. .UNINDENT .SH EXAMPLES .sp Typical usage: .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C rbd\-replay\-many host\-0 host\-1 \-\-original\-image=image \-\- \-c ceph.conf replay.bin .ft P .fi .UNINDENT .UNINDENT .sp This results in the following commands being executed: .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C ssh host\-0 \(aqrbd\-replay\(aq \-\-map\-image \(aqimage=image\-0\(aq \-c ceph.conf replay.bin ssh host\-1 \(aqrbd\-replay\(aq \-\-map\-image \(aqimage=image\-1\(aq \-c ceph.conf replay.bin .ft P .fi .UNINDENT .UNINDENT .SH AVAILABILITY .sp \fBrbd\-replay\-many\fP is part of Ceph, a massively scalable, open-source, distributed storage system.
