Hi, I now tried running locally hc-basic-suite-master with a patched OST, and it failed due to $subject. I checked and see that this also happened on CI, e.g. [1], before it started failing to to an unrelated reason later: E TASK [gluster.infra/roles/firewall_config : Add/Delete services to firewalld rules] *** E failed: [lago-hc-basic-suite-master-host-0] (item=glusterfs) => {"ansible_loop_var": "item", "changed": false, "item": "glusterfs", "msg": "ERROR: Exception caught: org.fedoraproject.FirewallD1.Exception: INVALID_SERVICE: 'glusterfs' not among existing services Permanent and Non-Permanent(immediate) operation, Services are defined by port/tcp relationship and named as they are in /etc/services (on most systems)"} E failed: [lago-hc-basic-suite-master-host-2] (item=glusterfs) => {"ansible_loop_var": "item", "changed": false, "item": "glusterfs", "msg": "ERROR: Exception caught: org.fedoraproject.FirewallD1.Exception: INVALID_SERVICE: 'glusterfs' not among existing services Permanent and Non-Permanent(immediate) operation, Services are defined by port/tcp relationship and named as they are in /etc/services (on most systems)"} E failed: [lago-hc-basic-suite-master-host-1] (item=glusterfs) => {"ansible_loop_var": "item", "changed": false, "item": "glusterfs", "msg": "ERROR: Exception caught: org.fedoraproject.FirewallD1.Exception: INVALID_SERVICE: 'glusterfs' not among existing services Permanent and Non-Permanent(immediate) operation, Services are defined by port/tcp relationship and named as they are in /etc/services (on most systems)"} This seems similar to [2], and indeed I can't see the package 'glusterfs-server' installed locally on host-0. Any idea? Thanks and best regards, [1] https://jenkins.ovirt.org/job/ovirt-system-tests_hc-basic-suite-master/2088/ [2] https://github.com/oVirt/ovirt-ansible/issues/124 -- Didi
