#
# When the plugin is stopped or leaves in error, while changing
# from single primary mode to multi primary mode, if the member did
# already set the single primary mode flag to false, then update
# everywhere checks shall be true afer stop.
#
# When the plugin is stopped or leaves in error, plugin configurations
# when the configuration change terminates must be valid,
# even if not persisted with SET PERSIST.
#
# Test:
# 0. This test requires three servers
# 1. Server1 start and bootstrap the group
# 2. Start server2
# 3. Start server3 and fake a stopped applier
# 4. Execute action to switch to multi primary
# 5. Server3 will leave group
# 6. Server3 changed to ERROR state
# 7. Check that Single primary mode is false on the stuck member and the
# update everywhere checks are true
# 8. Reap action executed
# 9. Cleanup
