loadbalancer can't create with chinese character name

[xuchaochao]

When create a loadbalancer with chinese character name, It will have some problems. Because its name will be written in haproxy configuration, but chinese character can't be written correctly.

- version of Neutron server and Neutron LBaaS plugin are both mitaka
- cat /var/log/neutron/lbaasv2-agent.log

HAProxy configuration is not exist

[Pawel Suder (pasuder)]

Thank you for your update. I would like to ask few more questions:

- please provide which version of Neutron server and Neutron LBaaS plugin or Octavia do you use
- would you like to provide logs (enabled DEBUG) from Neutron server and LBaaS/Octavia plugin, please?
- please provide command outputs and changes in HAProxy configuration, if it is possible

Thank you!

[Pawel Suder (pasuder)]

Thank you for your update. I would like to ask you if that issue could be reproduced on newer version, i.e. Newton?

[Brian Haley (brian-haley)]

I would actually ask if you could reproduce this in Pike or Queens, as those are the only upstream releases we will most likely even fix this in. Ocata is currently in security fix only mode, so any fixes for those will have to be in downstream distros.

Marking invalid here to move the bug over to the neutron-lbaas storyboard.
