Solution Verified - Updated

Environment

  • After applying the audit patch from below resolution, the upgrade fails again with the following error:

    rake aborted! Unable to create bookmark: Name has already been taken

Resolution

For Red Hat Satellite 6.2:

 # cd /usr/share/foreman #Go to foreman directory
 # cp db/seeds.rb db/seeds.rb.bak  #Take a backup of affected files:
 # patch -p1 < audit-6.2-patch.txt #Download the attached `audit-6.2.patch` in the current directory and apply the patch
 # foreman-maintain upgrade run --target-version 6.3 #Re-run satellite upgrade

For Red Hat Satellite 6.3:

# cd /usr/share/foreman #Go to foreman directory
# cp lib/seed_helper.rb lib/seed_helper.rb.bak #Take a backup of affected files
# patch -p1 < audit-6.3-patch.txt #Download the attached `audit-6.3.patch` in the current directory and apply the patch
# foreman-maintain upgrade run --target-version 6.4 #Re-run satellite upgrade

For Red Hat Satellite 6.4, 6.5 and 6.6:

   # cd /usr/share/foreman #Go to foreman directory
   # cp lib/seed_helper.rb lib/seed_helper.rb.bak #Take a backup of affected files
   # patch -p1 < audit-6.4_6.5_6.6-patch.txt #Download the attached `audit-6.4_6.5_6.6-patch.txt` in the current directory and apply the patch
   # satellite-maintain upgrade run --target-version <Satellite Target Version> #Re-run satellite upgrade
  • You can also re-run the satellite upgrade via "satellite-installer" command:
# satellite-installer --scenario satellite --upgrade
  • Note that "satellite-maintain" and "foreman-maintain" run more tests in the pre-upgrade phase, so these are the preferred methods

Bookmark Creation error after applying the patch:

# echo 'Bookmark.find_by_name("list hypervisors").destroy' | foreman-rake console #Remove the default subscription bookmarks
# echo 'Bookmark.find_by_name("future").destroy' | foreman-rake console
# echo 'Bookmark.find_by_name("expiring soon").destroy' | foreman-rake console
# foreman-rake db:seed --trace #Run db:seed to recreate the default subscription bookmarks
# satellite-maintain upgrade run --target-version <Satellite Target Version> #Re-run satellite upgrade

Root Cause

  • Several audits related to bookmark records are corrupt.
  • The corrupted bookmark might remain after applying the patch, so removing it and then recreation by running db:seed could help

Diagnostic Steps

  • Satellite upgrade fails with error rake aborted! NoMethodError: undefined method 'first' for nil:NilClass

    • There is a known issue in bookmark related audit records, reported in This content is not included.Bugzilla 1543316

    • Observed the following traceback in the /var/log/foreman/foreman-installer/satellite.log:

  • After applying the audit patch the upgrade fails again, because the bookmark's name had already been taken:
