It's generally easy to upgrade. Just switch your Ceph yum repo from
jewel to luminous.
Then update `librbd` on your hypervisors and migrate your VM's. It's
fast and without downtime of your VM's.

I don't config route table for them.

It's not clear what the problem is to me. Please try increasing the
debugging on your MDS and share a snippet (privately to me if you
