Trying to install oVirt hosted engine on a dedicated host in Data Centre. But it keeps failing at what looks to be the point where it is trying to get an IP if virbr0, which has been created successfully during setup, but does not appear to have an ip address. Any idea what could be going worng? System is running Centos 7.6.1810 Interface: em1 (public ip) Interface: em2 management network. This is the error in the log [ INFO ] TASK [ovirt.hosted_engine_setup : Fetch IPv4 CIDR for virbr0] [ ERROR ] fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'ipv4'\n\nThe error appears to have been in '/usr/share/ansible/roles/ovirt.hosted_engine_setup/tasks/bootstrap_local_vm/01_prepare_routing_rules.yml': line 57, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n tags: ['skip_ansible_lint']\n - name: Fetch IPv4 CIDR for {{ virbr_default }}\n ^ here\nWe could be wrong, but this one looks like it might be an issue with\nmissing quotes. Always quote template expression brackets when they\nstart a value. For instance:\n\n with_items:\n - {{ foo }}\n\nShould be written as:\n\n with_items:\n - \"{{ foo }}\"\n"} [ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook

low power, low cost glusterfs storage
by Jonathan Baecker 04 Mar '19

04 Mar '19

Hello everybody! Does anyone here have experience with a cheap, energy-saving glusterfs storage solution? I'm thinking of something that has more power than a rasbian Pi, 3 x 2 TB (SSD) storage, but doesn't cost much more and doesn't consume much more power. Would that be possible? I know the "Red Hat Gluster Storage" requirements, but are they generally so high? Only a few VM images would have to be on it... Greetings Jonathan
