Since this issue was entered in bugzilla without a release flag set, rhos-8.0? has been automatically added to ensure that it is properly evaluated for this release.

First of all, this bug is not directly related to ironic and/or inspector ("thanks" to bulk start command for being so confusing). I think the root cause is that we've dropped the ironicclient patch for bumping retries number. tripleoclient must do it now instead when trying to update node provision state.

Ofer, could you explain why you changed the component? This error does not even involve discoverd. I've set it to the correct component previously.

Hi

We don't have python-rdomanager-oscplugin in OSPd8 so i moved it to ironic 

I will move it to ospd
