hosted_engine_setup fails when done remotedly.

[kristvanbesien]

SUMMARY

The hosted_engine_setup role does not work when executed from a remote host.

COMPONENT NAME

Role hosted_engine_setup

STEPS TO REPRODUCE

Inventory:

# Settings for the hosted engine 
he_bridge_if: bond0
he_fqdn:***
he_shortname: "{{ he_fqdn.split('.')[0] }}"
he_vm_ip_addr: 10.123.250.18
he_vm_ip_prefix: 29
he_vm_dns_addr: ['10.0.80.11','10.0.80.12']
he_default_gateway: 10.123.250.17 
he_vm_etc_hosts: true
he_domain_type: iscsi
he_cluster: management
he_datacenter: management
he_appliance_password: "{{ login_password }}"
he_admin_password: "{{ login_password }}"
he_mem_size_MB: "4096"
he_vcpus: 4
he_storage_domain_addr: "{{ iscsi_portal }}"
he_iscsi_portal_port: "3260"
he_iscsi_tpgt: "1"
he_iscsi_target: "{{ iscsi_target }}"
he_lun_id": "{{ iscsi_lun }}"

- name: Deploy oVirt hosted engine
  hosts: ***

  vars: 
     he_host_name: "{{ inventory_hostname}}"
     he_host_address: "{{ private_ip }}"    
    
  roles:
     - role: hosted_engine_setup
  collections:
     - redhat.rhv

EXPECTED RESULTS

Hosted engine is deployed.

ACTUAL RESULTS

Process hangs until it times out at:

TASK [redhat.rhv.hosted_engine_setup : Wait for the local VM] ***********************************************************************

This is probably due to the following in full_execution.yaml

- name: Local engine VM installation - Pre tasks
  block:
    - name: 03 Bootstrap local VM
      import_tasks: bootstrap_local_vm/03_engine_initial_tasks.yml
      delegate_to: "{{ groups.engine[0] }}"

I suspect that groups.engine[0] refers to the temporary IP of the HE on the local bridge. This is not accessible from outside the host.

[kristvanbesien]

It turns out to be a bit more complicated...

The playbook is not hanging, it is just proceeding very slowly. This is an example of the output:

TASK [redhat.rhv.hosted_engine_setup : Wait for the local VM] ***********************************************************************
[WARNING]: sftp transfer mechanism failed on [mgg-rhvmgt-fra5.mgg.local]. Use ANSIBLE_DEBUG=1 to see detailed information
[WARNING]: scp transfer mechanism failed on [mgg-rhvmgt-fra5.mgg.local]. Use ANSIBLE_DEBUG=1 to see detailed information
ok: [mgg-mgt001-fra5.mgg.local -> mgg-rhvmgt-fra5.mgg.local]

TASK [redhat.rhv.hosted_engine_setup : Add an entry for this host on /etc/hosts on the local VM] ************************************
[WARNING]: sftp transfer mechanism failed on [mgg-rhvmgt-fra5.mgg.local]. Use ANSIBLE_DEBUG=1 to see detailed information
[WARNING]: scp transfer mechanism failed on [mgg-rhvmgt-fra5.mgg.local]. Use ANSIBLE_DEBUG=1 to see detailed information

So ansible tries to upload the module, first tries sftp, then scp, then something else (what?)

[arachmani]

@kristvanbesien Can you please share the ovirt-hosted-engine-setup log files from the host
and the engine.log from the localVM (the engine)?

You should find the IP address of the localVM in /etc/hosts
or you can use virsh -r net-dhcp-leases default .
