Had you run a search for that couldn't finalize options: -34 error, you would have discovered the existing Ceph bug and the mailing list thread discussing it where they say that the name= is too long. You should try to shorten the name, maybe by removing kubernetes-dynamic- from the name.
Since you didn't include any version information in your question, no one can say whether the recent release of 14.2.7 will help you or not, but it contains security updates so if you're not running 14.2.7 already, you are strongly encouraged to upgrade anyway.
