Error 'ascii' codec can't decode in introspection nodes overcloud

[Juan Manuel Torres]

I use CentOS 7 for undercloud.
I execute "openstack baremetal introspection bulk start" for introspection in two nodes in KVM. I use images from https://repos.fedorapeople.org/repos/openstack-m/rdo-images-centos-liberty-opnfv/

Error in node.

Hi!

You have 2 errors, and there seems to be something wrong with the images you use.

First, failed to run hardware-detect utility: [Errno 2] No such file or directory: there was a change to install the "python-hardware-detect" package, your images were not updated since then.

Second, the bug about encodings was fixed in ironic-python-agent 1.0.1 which was released on 2016-01-11. Your images are from 2016-01-07 and probably don't have the fix.

Could you please try with more recent images?

[Juan Manuel Torres (juanmanuel-torres)]

Thx for you andswer, when I have time again will deploy the stage.

@Juan,

Could you also tell us how you found https://repos.fedorapeople.org/repos/openstack-m/rdo-images-centos-liberty-opnfv/ ? Those images were put there solely to help opnfv apex team, and I plan to remove them. However, if they are linked in some document, I would like to update it first.

I need reinstall undercloud? I build images of new and no generate complety? (images3)

@Trown

I found it by searching in Google this error

Command: openstack overcloud image build --all

Error: Required file "ironic-python-agent.initramfs" does not exist.

I think you'd better use images from https://ci.centos.org/artifacts/rdo/images/ (pick your release).
