Timur, the error Sergii mentioned in the comment above has nothing to do with the fact you have separate nodes for keystone and database: it says that file injection did not work for some reason.
Are you sure the very same test pass in your usual runs? (without separated components) For the case when ephemeral disks are stored in Ceph, it's expected that file injection won't work.
