FlashBlade Driver

Overview

The FlashBlade driver does not support share server management ind is therefore considered a DHSS=False type driver.

Installation

Important

The FlashBlade Manila driver is not currently upstream in OpenStack Manila and therefore needs to be manually installed in a running Manila configuration. This driver is only supported on a Best Efforts basis and there is currently no official support from Pure Storage.

Perform the following steps to install the driver.

Locate the manila directory for your OpenStack deployment and create the following directory

manila/share/drivers/purestorage
Copy the FlashBlade driver file into this new directory

cd manila/share/drivers/purestorage wget https://raw.githubusercontent.com/PureStorage-OpenConnect/OpenStack-Manila/master/manila/share/drivers/purestorage/flashblade.py .
Edit the file manila/opts.py and perform the following actions:
- Near the beginning of the file with the import commands and add
  
  import manila.share.drivers.purestorage.flashblade
- Find the _global_opt_lists section and add the following lines
  
  manila.share.drivers.purestorage.flashblade.flashblade_auth_opts, manila.share.drivers.purestorage.flashblade.flashblade_extra_opts, manila.share.drivers.purestorage.flashblade.flashblade_connection_opts,

Setup

To set up the FlashBlade driver without Share Server, the following stanza should be added to the Manila configuration file (manila.conf):

[flashblade]
share_backend_name = flashblade
share_driver = manila.share.drivers.purestorage.flashblade.FlashBladeShareDriver
driver_handles_share_servers = False
flashblade_mgmt_vip = FlashBlade management VIP
flashblade_data_vip = FlashBlade data VIP
flashblade_api = FlashBlade API token
flashblade_eradicate = { True | False }

Be sure that the value of the enabled_share_backends option in the [DEFAULT] stanza includes the name of the stanza you chose for the backend.
The value of driver_handles_share_servers MUST be set to False.

After completing the configuration of the Manila configuration file you must restart all of the Manila services to enable the FlashBlade driver.
