Getting error while executing task gluster.infra/roles/backend_setup

[rkothiya]

While trying to run gluster-performance-test-suite using centos7 as the control machine, I am getting the following error :

TASK [gluster.infra/roles/backend_setup : Make sure meta and pool pvs exists in volume group] ******************************************************************************
fatal: [server1.com]: FAILED! => {"msg": "dict2items requires a dictionary, got <class 'ansible.template.AnsibleUndefined'> instead."}
fatal: [server2.com]: FAILED! => {"msg": "dict2items requires a dictionary, got <class 'ansible.template.AnsibleUndefined'> instead."}
fatal: [server3.com]: FAILED! => {"msg": "dict2items requires a dictionary, got <class 'ansible.template.AnsibleUndefined'> instead."}
fatal: [server4.com]: FAILED! => {"msg": "dict2items requires a dictionary, got <class 'ansible.template.AnsibleUndefined'> instead."}
fatal: [server5.com]: FAILED! => {"msg": "dict2items requires a dictionary, got <class 'ansible.template.AnsibleUndefined'> instead."}
fatal: [server6.com]: FAILED! => {"msg": "dict2items requires a dictionary, got <class 'ansible.template.AnsibleUndefined'> instead."}

The pvs are existing on the machine and it is working fine with fedora32, hence I think this is a bug. The following gluster-ansible packages were installed on the centos7 machine from the copr repo :

# rpm -qa | grep gluster-ansible 
gluster-ansible-cluster-1.0.1-2.el7.noarch
gluster-ansible-1.0.5-1.el7.noarch
gluster-ansible-maintenance-1.0.1-3.el7.noarch
gluster-ansible-infra-1.0.4-10.el7.noarch
gluster-ansible-repositories-1.0.1-2.el7.noarch
gluster-ansible-features-1.0.5-6.el7.noarch

Centos Version :

# cat /etc/redhat-release 
CentOS Linux release 7.4.1708 (Core) 

Important Note: I am not getting any problems while using fedora32

@rkothiya can you share your playbook here? this probably might be because centos might not have updated latest builds @gobindadas i think centos might require an updated build gobinda, will check again, but if it requires, im still yet to be sponsored.

We are trying to run this project, using centos as the control machine: Gluster performance test suite

So the centos builds are upto date, the issue was ( ansible --version) was using python2 instead of python3 ,in centos 7 machine, which caused this error

If anyone else faces this issue while using this repo on centos/RHEL7 , do check the python version in ansible (since centos 7 heavly rely on python2 )

closing this issue
