Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Rich Megginson 2022-04-28 02:17:01 UTC
I was testing the role for the first time and wanted to run it in --check mode to verify the behaviour, but it would fail. Here is the error

TASK [linux-system-roles.storage : get required packages] *****************************************************************************
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: NameError: name 'devices' is not defin

I googled the problem and came across this Red Hat KB article:
https://access.redhat.com/solutions/6726561

I am already using Python 3, and was using localhost with connection = local.

I tried to run the playbook in regular (not --check) mode, and it ran perfectly. Subsequent executions of the playbook in --check mode generate no errors either. I have reproduced the issue on two separate machines.
Steps to generate the error

    Create a playbook that uses this role
    Run in check mode - Result = error as per above
    Run same playbook in regular mode - Result = success
    Run in check mode again - Result = success

Environment info

OS: Fedora 32 (also reproducible on Fedora 35)
Ansible version: ansible-2.9.21-1.fc32.noarch AND ansible-2.9.27-1.fc35.noarch
Link to the playbook I am testing with:
