[ovirt-users] Re: Latest ManagedBlockDevice documentation

I hadn't installed the necessary packages when the engine was first installed. However, running 'engine-setup --reconfigure-optional-components' doesn't work at the moment because (by design) my engine does not have a network route outside of the cluster. It fails with: [ INFO ] DNF Errors during downloading metadata for repository 'AppStream': - Curl error (7): Couldn't connect to server for http://mirrorlist.centos.org/?release=8&arch=x86_64&repo=AppStrea... [Failed to connect to mirrorlist.centos.org port 80: Network is unreachable] [ ERROR ] DNF Failed to download metadata for repo 'AppStream': Cannot prepare internal mirrorlist: Curl error (7): Couldn't connect to server for http://mirrorlist.centos.org/?release=8&arch=x86_64&repo=AppStrea... [Failed to connect to mirrorlist.centos.org port 80: Network is unreachable] I have a proxy set in the engine's /etc/dnf/dnf.conf, but it doesn't seem to be obeyed when running engine-setup. Is there another way that I can get engine-setup to use a proxy? --Mike On 9/30/20 2:19 AM, Benny Zlotnik wrote: > When you ran `engine-setup` did you enable cinderlib preview (it will > not be enabled by default)? > It should handle the creation of the database automatically, if you > didn't you can enable it by running: > `engine-setup --reconfigure-optional-components` > > > On Wed, Sep 30, 2020 at 1:58 AM Michael Thomas <wart(a)caltech.edu&gt; wrote: >> >> Hi Benny, >> >> Thanks for the confirmation.
