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

NAME
       rbd-replay-many - replay	a rados	block device (RBD) workload on several
       clients

SYNOPSIS
       rbd-replay-many [ options ] --original-image name host1 [ host2 [ ... ] ] -- rbd_replay_args

DESCRIPTION
       rbd-replay-many is a utility for	replaying a rados block	 device	 (RBD)
       workload	 on  several clients.  Although	all clients use	the same work-
       load, they replay against separate images.  This	matches	normal use  of
       librbd, where each original client is a VM with its own image.

       Configuration and replay	files are not automatically copied to clients.
       Replay images must already exist.

OPTIONS
       --original-image	name
	      Specifies	the name (and snap) of the  originally	traced	image.
	      Necessary	for correct name mapping.

       --image-prefix prefix
	      Prefix  of  image	 names	to  replay  against.  Specifying --im-
	      age-prefix=foo  results  in  clients  replaying  against	foo-0,
	      foo-1, etc.  Defaults to the original image name.

       --exec program
	      Path to the rbd-replay executable.

       --delay seconds
	      Delay between starting each client.  Defaults to 0.

EXAMPLES
       Typical usage:

	  rbd-replay-many host-0 host-1	--original-image=image -- -c ceph.conf replay.bin

       This results in the following commands being executed:

	  ssh host-0 'rbd-replay' --map-image 'image=image-0' -c ceph.conf replay.bin
	  ssh host-1 'rbd-replay' --map-image 'image=image-1' -c ceph.conf replay.bin

AVAILABILITY
       rbd-replay-many	is  part  of  Ceph, a massively	scalable, open-source,
       distributed storage system. Please refer	to the Ceph  documentation  at
       http://ceph.com/docs for	more information.
