.SH DESCRIPTION
|
||
|
|
.sp
|
||
|
|
\fBrbd\-replay\-many\fP is a utility for replaying a rados block device (RBD) workload on several clients.
|
||
|
|
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.
|
||
|
|
