.SH DESCRIPTION
|
|
.sp
|
|
\fBceph\-syn\fP is a simple synthetic workload generator for the Ceph
|
|
distributed file system. It uses the userspace client library to
|
|
generate simple workloads against a currently running file system. The
|
|
file system need not be mounted via ceph\-fuse(8) or the kernel client.
|
|
.sp
|
|
One or more \fB\-\-syn\fP command arguments specify the particular
|
|
workload, as documented below.
|
|
.SH OPTIONS

|
.UNINDENT
|
|
.INDENT 0.0
|
|
.TP

|
|
startup.

.INDENT 0.0
|
|
.TP
|
|
.B \-m monaddress[:port]

.INDENT 0.0
|
|
.TP
|
|
.B \-\-syn workloadspec
|
|
Run the given workload. May be specified as many times as
|
|
needed. Workloads will normally run sequentially.
|
|
.UNINDENT

|
.SH WORKLOADS
|
|
.sp

|
.TP
|
|
.B \fBwritefile\fP \fIsizeinmb\fP \fIblocksize\fP

Create a file, named after our client id, that is \fIsizeinmb\fP MB by
|
|
writing \fIblocksize\fP chunks.
|
|
.TP
|
|
.B \fBreadfile\fP \fIsizeinmb\fP \fIblocksize\fP
