[ovirt-users] Re: oVirt Node 4.4.1.1 Cockpit Hyperconverged Gluster deploy fails insufficient free space no matter how small the volume is set

Dear Strahil, Dominique and Edward: I reimaged the three hosts with ovirt-node-ng-installer-4.4.1-2020071311.el8.iso just to be sure everything was stock (I had upgraded from v4.4) and attempted a redeploy with all suggested changes EXCEPT replacing "package" with "dnf" --> same failure. I then made Strahil's recommended replacement of "package" with "dnf" and the Gluster deployment succeeded through that section of main.yml only to fail a little later at: - name: Install python-yaml package for Debian systems package: name: python-yaml state: present when: ansible_distribution == "Debian" or ansible_distribution == "Ubuntu" I found this notable given that I had not replaced "package" with "dnf" in the prior section: - name: Change to Install lvm tools for debian systems. package: name: thin-provisioning-tools state: present when: ansible_distribution == "Debian" or ansible_distribution == "Ubuntu" and deployment had not failed here. Anyhow, I deleted the two Debian statements as I am deploying from Node (CentOS based), cleaned up, cleaned up my drives ('dmsetup remove eui.xxx...' and 'wipefs --all --force /dev/nvme0n1 /dev/nvmeXn1 ...') and redeployed again. This time Gluster deployment seemed to execute main.yml OK only to fail in a new file, vdo_create.yml: TASK [gluster.infra/roles/backend_setup : Install VDO dependencies] ************ task path: /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/vdo_create.yml:26 fatal: [fmov1n1.sn.dtcorp.com]: FAILED! => {"changed": false, "msg": "The Python 2 yum module is needed for this module. If you require Python 3 support use the `dnf` Ansible module instead."} fatal: [fmov1n3.sn.dtcorp.com]: FAILED! => {"changed": false, "msg": "The Python 2 yum module is needed for this module. If you require Python 3 support use the `dnf` Ansible module instead."} fatal: [fmov1n2.sn.dtcorp.com]: FAILED! => {"changed": false, "msg": "The Python 2 yum module is needed for this module. If you require Python 3 support use the `dnf` Ansible module instead."} Expecting that this might continue, I have been looking into the documentation of how "package" works and if I can find a root cause for this rather than reviewing n *.yml files and replacing "package" with "dnf" in all of them. Thank you VERY much to Strahil for helping me! If Strahil or anyone else has any additional troubleshooting tips, suggestions, insight or solutions I am all ears. I will continue to update as I progress. Respectfully, Charles
