Resolution

• This issue has been reported to the Red Hat Engineering team via This content is not included.Bugzilla 1961770 and expected to be fixed in an upcoming minor release of Satellite 6.9.

• For now, Upgrading to wiredTiger engine is not a mandatory step to perform. One can continue using the mmapv1 mongo engine as usual while on Satellite\Capsule 6.9.

  • In this situation, simply restart the services of the affected server and continue working with the same.

    # foreman-maintain service restart
    # sleep 20 && hammer ping
    

• But if it's still an end-user requirement to upgrade to wiredTiger mongo engine, please contact This content is not included.Red Hat Technical Support to work around the issue properly and continue with the upgrade.
