Hi Guys, I am trying to install a new cluster... I currently have a 9 node and two 6 node oVirt Clusters... (these were installed on 4.1 and upgraded to 4.2) So i want to build a new cluster, which is working fine on this HP notebook i use for testing (using single node gluster deployment) But when i try install this on my production servers which are Cisco UCS servers i keep getting this error: [ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is "[Error creating a storage domain]". HTTP response code is 400. [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Error creating a storage domain]\". HTTP response code is 400."} This happens during storage creation after the hosted-engine is built and after gluster has been deployed (error happens for both single and 3 replica deployments) I just cant see how an install on one type of server is successful but not on the UCS servers (which i am running my other ovirt clusters on) BTW i dont think the issue is related to Gluster Storage Create as i tried using NFS and Local storage and get the same error (on UCS server only) I am using the ovirt-node-ng-installer-4.2.0-2019011406.el7.iso install ISO Below is a tail from ovirt-hosted-engine-setup-ansible-create_storage_domain Log file 2019-01-27 11:09:49,754+0400 INFO ansible ok {'status': 'OK', 'ansible_task': u'Fetch Datacenter name', 'ansible_host': u'localhost', 'ansible_playbook': u'/usr/share/ovirt-hosted-engine-setup/ansible/create_storage_domain.yml', 'ansible_type': 'task'} 2019-01-27 11:09:49,754+0400 DEBUG ansible on_any args <ansible.executor.task_result.TaskResult object at 0x7f9f9b7e2d50> kwargs 2019-01-27 11:09:50,478+0400 INFO ansible task start {'status': 'OK', 'ansible_task': u'Add NFS storage domain', 'ansible_playbook': u'/usr/share/ovirt-hosted-engine-setup/ansible/create_storage_domain.yml', 'ansible_type': 'task'} 2019-01-27 11:09:50,479+0400 DEBUG ansible on_any args TASK: Add NFS storage domain kwargs is_conditional:False 2019-01-27 11:09:51,151+0400 DEBUG var changed: host "localhost" var "otopi_storage_domain_details_nfs" type "<type 'dict'>" value: "{ "changed": false, "skip_reason": "Conditional result was False", "skipped": true }" 2019-01-27 11:09:51,151+0400 INFO ansible skipped {'status': 'SKIPPED', 'ansible_task': u'Add NFS storage domain', 'ansible_host': u'localhost', 'ansible_playbook': u'/usr/share/ovirt-hosted-engine-setup/ansible/create_storage_domain.yml', 'ansible_type': 'task'} 2019-01-27 11:09:51,151+0400 DEBUG ansible on_any args <ansible.executor.task_result.TaskResult object at 0x7f9f9b7e2610> kwargs 2019-01-27 11:09:51,820+0400 INFO ansible task start {'status': 'OK', 'ansible_task': u'Add glusterfs storage domain', 'ansible_playbook': u'/usr/share/ovirt-hosted-engine-setup/ansible/create_storage_domain.yml', 'ansible_type': 'task'} 2019-01-27 11:09:51,821+0400 DEBUG ansible on_any args TASK: Add glusterfs storage domain kwargs is_conditional:False 2019-01-27 11:10:02,045+0400 DEBUG var changed: host "localhost" var "otopi_storage_domain_details_gluster" type "<type 'dict'>" value: "{ "changed": false, "exception": "Traceback (most recent call last):\n File \"/tmp/ansible_ovirt_storage_domain_payload_Xous24/__main__.py\", line 682, in main\n ret = storage_domains_module.create()\n File \"/tmp/ansible_ovirt_storage_domain_payload_Xous24/ansible_ovirt_storage_domain_payload.zip/ansible/module_utils/ovirt.py\", line 587, in create\n **kwargs\n File \"/usr/lib64/python2.7/site-packages/ovirtsdk4/services.py\", line 24225, in add\n return self._internal_add(storage_domain, headers, query, wait)\n File \"/usr/lib64/python2.7/site-packages/ovirtsdk4/service.py\", line 232, in _internal_add\n return future.wait() if wait else future\n File \"/usr/lib64/python2.7/site-packages/ovirtsdk4/service.py\", line 55, in wait\n return self._code(response)\n File \"/usr/lib64/python2.7/site-packages/ovirtsdk4/service.py\", line 229, in callback\n self._check_fault(response)\n File \"/usr/lib64/python2.7/site-packages/ovirtsdk4/service.py\", line 132, in _check_fault\n self._raise_error(response, body)\n File \"/usr/lib64/python2.7/site-packages/ovirtsdk4/service.py\", line 118, in _raise_error\n raise error\nError: Fault reason is \"Operation Failed\".
