--- Scott Dodson 2018-02-20 10:02:45 EST After discussing the solution we're going to implement is to document the expected PATH and request that admins ensure that PATH is correct for both ansible_ssh_user and root. This would be the default for RHEL 7. We feel that it's incorrect to alter all code paths to use explicit paths when those paths may change between OS releases and it's undesirable to write conditional logic for every binary we use. --- The default path for the root user in RHEL is `/sbin:/bin:/usr/sbin:/usr/bin`. If the user has these directories in their PATH then the openshift-ansible installer should succeed without issue. https://github.com/openshift/openshift-docs/pull/7869 LGTM. |
Description of problem: Running the "v3_6 upgrade_control_plane" playbook failed on openshift_node_upgrade 'Disable swap' task, due to swapoff command not found, and failed on openshift_node_upgrade 'Reset selinux context' task, due to "restorecon command not found. Version-Release number of selected component (if applicable): During upgrade from 3.5.5.31 to 3.6.173.0.5, using ansible-2.2.3.0 & atomic-openshift-utils-3.6.173.0.48, but customer reports this has been an issue since 3.3 install. How reproducible: Repeatedly, until modifying specific playbook, to prepend commands with "/sbin/", or updating PATH via environment directive. Steps to Reproduce: 1.ansible-playbook /usr/share/ansible/openshift-ansible/playbooks/byo/openshift-cluster/upgrades/v3_6/upgrade_control_plane.yml Actual results: TASK [openshift_node_upgrade : Disable swap] *********************************** fatal: [denqca3osmas01.qic.tiaa-cref.org]: FAILED! => { "changed": false, "cmd": "swapoff --all", "failed": true, "rc": 2 } MSG: [Errno 2] No such file or directory AND TASK [openshift_node_upgrade : Reset selinux context] ************************** fatal: [denqca3osmas01.qic.tiaa-cref.org]: FAILED! => { "changed": false, "cmd": "restorecon -RF /var/lib/origin/openshift.local.volumes", "failed": true, "rc": 2 } MSG: [Errno 2] No such file or directory Expected results: The upgrade_control_plane playbook upgrades master nodes. Additional info: This is likely due to customer's "secured non-tty ssh session environment" not including /sbin in the PATH. See customer Support Case https://access.redhat.com/support/cases/#/case/02037064 for logs Description of problem: Version-Release number of the following components: rpm -q openshift-ansible rpm -q ansible ansible --version How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Please include the entire output from the last TASK line through the end of output if an error is generated Expected results: Additional info: Please attach logs from ansible-playbook with the -vvv flag
