Hi all, I am trying to build some cloud again and failing with [1]. I think this is a most critical line. It fails during GRUB2 deployment on overcloud image, I believe main error message is: mount: only root can do that. I used the following steps to create image: cp -ar /etc/yum.repos.d repos # enable: repos/CentOS-HA.repo sed -i "s/enabled=0/enabled=1/g" repos/CentOS-Linux-HighAvailability.repo sed -i "s/gpgcheck=1/gpgcheck=0/g" repos/*repo export DIB_YUM_REPO_CONF="$(ls $(pwd)/repos/*repo)" export STABLE_RELEASE="ussuri" source /home/stack/stackrc mkdir /home/stack/images cd /home/stack/images openstack overcloud image build --config-file /home/stack/overcloud-images-python3.yaml openstack overcloud image upload --update-existing # openstack overcloud node configure --all-manageable overcloud-images-python3.yaml file content can be found here [2], just added additional packages, such as tcpdump, iperf, iptraf and so on... And steps from link [3] to set root pass to troubleshoot if needed. any thoughts? Maybe there were some changes recently (from 22 of December) PRevious images from there. Thank you for your thoughts and attention.
