[ovirt-users] Re: ovirt 4.4.1.1 hci and problems with ansible 2.9.10 and/or missing python2
Hello Gianluca,
thanks for opening the bug. I have also reported my test scenario below.
(One thing more in my case, the standalone Manager needs to be installed on EL8
and not like documents says on EL7.
With EL7 load is gives an error that Engine for EL7 is not avaiable. Document
needs to be updated.)
---
The same error occurs when trying to add a node to a standalone Engine Manager.
Steps to Reproduce:
1. install a standalone Engine Manager on EL8 step by step with this
documentation
https://www.ovirt.org/documentation/installing_ovirt_as_a_standalone_manager_with_local_databases/#Installing_the_Red_Hat_Virtualization_Manager_SM_localDB_deploy
2. install a node using ovirt-node-ng-installer-4.4.1-2020071311.el8.iso
3. try to add the node inside the Engine Manager

I've reverified that install new host, check for upgrades, upgrade host and
enroll certificates work fine even with ansible 2.9.10 on standalone engine
installation. So there is some issue inside HCI installer, which doesn't
handle python interpreter correctly.
Gianluca, could you please create a bug for that?
Thanks,
Martin

I have a very clean install from 4.1.1.1 node ng iso anf I'm the third
to notice that with this release.
The engine deployment is going on. Not finished yet, but to have ti go
I had to modify, with the same strategy ("use: dnf" with package module and
use "package" instead of "yum" and also specifying "use: dnf") in these
files under /usr/share/ansible/roles:
ovirt.engine-setup/tasks/engine_setup.yml
ovirt.engine-setup/tasks/install_packages.yml

Hm...
but then setting that variable to python3 should work, but based on the list
reports - it doesn't work.

Hi Gianluca,
that's very strange error, because I'm 100% sure we are using yum
module with Python3 in several other roles including adding host to engine
or upgrading host and so far I haven't heard any issue with ansible 2.9.10
and yum module.
Gobinda, wouldn't enforcing python interpreter version help there?

The engine deployment failed in the phase where it tries to add the host
and waits for the host to be up and if I go into the logs in
/var/log/ovirt-hosted-engine-setup/engine-logs-2020-07-17T08:30:48Z/ovirt-engine/host-deploy/
the file
ovirt-host-deploy-ansible-20200717104103-novirt2.example.net-3a710f0c.log
contains
020-07-17 10:41:17 CEST - fatal: [novirt2.example.net]: FAILED! =>
{"changed": false, "module_stderr": "/bin/sh: /usr/bin
/python2: No such file or directory\n", "module_stdout": "", "msg": "The
module failed to execute correctly, you probably
need to set the interpreter.\nSee stdout/stderr for the exact error", "rc":
127}
2020-07-17 10:41:17 CEST - {
"status" : "OK",
"msg" : "",
"data" : {
"uuid" : "00f4c6a8-8423-4a2a-bfd5-f38c34f56ecf",
"counter" : 53,
"stdout" : "fatal: [novirt2.example.net]: FAILED! => {\"changed\":

So I think I have to find and solve why it searches python2
I compared on an existing 4.4.0 environment I have (hci single node
installed from 4.4.0 node ng iso) and no python2 apparently there, only
ansible that is at ansible-2.9.9-1.el8.noarch instead of
ansible-2.9.10-1.el8.noarch of 4.4.1.1
Possibly any wrong default about python?
Alternatives seems the same between 4.4.0 and 4.4.1.1

Not sure where to search if not somehow a bug of ansible 2.9.10
Can I try to clean install a 4.4.1.1 host and downgrade ansible before
deploy, eg running
rpm -Uvh --oldpackage

The installation from the iso was with all default values.
The only "non standard" thing, if we want it to call this way is that
before running the wizard, on the host I pre-installed the appliance
package, to shorten the deploy phase hereafter.
And to do it I executed, because of habit:
yum install ovirt-engine-appliance
instead of "dnf install...", but I think this doesn't influence ansible
autodetect when using "package" module or the error about python2 when
using "yum" module...

notice that with this release.
The engine deployment is going on. Not finished yet, but to have ti go I
had to modify, with the same strategy ("use: dnf" with package module and
use "package" instead of "yum" and also specifying "use: dnf") in these
files under /usr/share/ansible/roles:
ovirt.engine-setup/tasks/engine_setup.yml
ovirt.engine-setup/tasks/install_packages.yml

Hi Gianluca,
that's very strange error, because I'm 100% sure we are using yum module
with Python3 in several other roles including adding host to engine or
upgrading host and so far I haven't heard any issue with ansible 2.9.10 and
yum module.
Gobinda, wouldn't enforcing python interpreter version help there?

Same problem for the next stage
[ INFO ] TASK [ovirt.hosted_engine_setup : Install oVirt Hosted Engine
packages]
[ ERROR ] fatal: [localhost]: FAILED! => {"attempts": 10, "changed": false,
"msg": "The Python 2 yum module is needed for this module. If you require

I think this is a major problem for new installations.
How can I get back python2 to see if it works without having to go through
all yaml files?
