[RHOSP13] Additional log details to troubleshoot the failure overcloud stack

Solution Verified - Updated -

Environment

  • Red Hat OpenStack v.13
  • Red Hat OpenStack v.14 specific log refer following KCS 3780751

Issue

  • How to collect additional information which requires to troubleshoot the RHOSP13 deployment?

Resolution

  • Refer Director Deployment Guide to troubleshoot the RHOSP13 deployment.

  • To review overcloud nodes with its associated resources, execute below script which extracts the required details to xxx_xxx_Overcloud_details.tar.gz and uploads the tar file to support case which has opened with Red Hat OpenStack.

Diagnosis Workflows and Executions Error

  • The OpenStack Workflow (mistral) service groups of multiple OpenStack tasks into workflows. It uses a set of these workflows to perform common functions across the CLI and web UI.
  • This includes bare metal node control, validations, plan management, and overcloud deployment.

  • OpenStack Workflow and action execution also provide robust logging of executions, To diagnosis, the workflow and action details, execute the below script and review the details in /tmp/xxx_workflow_xxx.log.

    cat<<'EOF'>mistral_action_troubleshoot.sh
    #!/bin/bash
    FS=$'\n' ;
    file=/tmp/`hostname`_workflow_`date '+%F_%H%m%S'`.log
    
    source /home/stack/stackrc
    stackname=`openstack stack list -c "Stack Name" -f value`
    
    echofun() {
      echo -e "\n\n$1" | tee -a $file
    }
    
    workflow(){
    echofun "[stack@`hostname`~]$ $1 "
    eval "$1" | tee -a $file

    do

    workflow "openstack action execution output show $i"
    done
    EOF
    
  • Execute the script:

    $ chmod +x mistral_action_troubleshoot.sh
    $ bash mistral_action_troubleshoot.sh
    
  • If this is for a case which was opened with Red Hat support, attach the resulting tar archive to the case.

SOS REPORT

  • Generate and provide a sosreport of the node which has impacted.

    sosreport -a --batch --all-logs
