ERF64-6496 [Foreman::MaintenanceException]: There are migrations pending in the system
This, however, is fairly easy to fix. First, try to fix it using foreman rake by migrating and seeding the db.
[archy@katello ~]$ sudo foreman-rake db:migrate [archy@katello ~]$ sudo foreman-rake db:seed
If this doesn't work, you could always to the 'universal' fix for foreman.
[archy@katello ~]$ sudo foreman-install --scenario katello --upgrade
Ideally, you should've created a snapshot before updating your katello / foreman instance.
When using KVM, this can be done using virsh
[root@hyv01 ~]# virsh snapshot-create --domain katello.archyslife.lan
