Important notes
----------------
StorPerf has added the ability to specify the number of Cinder Volumes per
agent VM to test. The name of the device that the volume is attached to
has been appended to the host IP address in the metrics so that it can be
tracked independently.
Summary
--------
StorPerf is a standalone framework that uses OpenStack to measure Cinder volume
performance. If desired, it can push results to the OPNFV Test Results DB, or
the embedded Graphite web interface can be used to perform ad hoc queries.
This release allows for changing of stack attributes from the OpenStack CLI.
Using a command such as
.. code-block::
heat stack-update StorPerfAgentGroup --existing -P "agent_count=6"
will change the existing stack to use 6 agents. Note that StorPerf can take
up to 1 minute after the stack update is complete before detecting the new
values. Please use a GET of the configurations API to test for updated
values prior to submitting a new test.
The following command changes the number of volumes per agent:
.. code-block::
heat stack-update StorPerfAgentGroup --existing -P "volume_count=2"

Version change
===============
Module version changes
-----------------------
No changes to any modules.
Reason for version
===================
* Loading stack properties from OpenStack could take minutes or longer
depending on the stack size. This version includes changes from SNAPS
to take advantage of parallel OpenStack object lookups.
Features additions
-------------------
* STORPERF-239 - Add IP addresses of slaves to configurations API
* STORPERF-245 - Change to use multithreaded SNAPS
Bug Fixes

Known Limitations, Issues and Workarounds
------------------------------------------
Limitations
============
Known issues
=============
* Cirros target VMs do not always mount Cinder volumes on first boot. Sometimes
a reboot of the VM is required to properly attach the Cinder volume to /dev/vdb
* A bug in the linux kernel can prevent Cinder volumes from attaching to VMs
using ARM architecture. Specifying the following properties in Glance for
the ARM based image will work around this problem. Note: this will cause
the device to show up as a SCSI device and therefore will be /dev/sdb instead
of /dev/vdb.
.. code-block:
--property hw_disk_bus=scsi --property hw_scsi_model=virtio-scsi
