Patrick brought up a good point in today’s Steering Committee call about migrating the LRC.  There is value in having a cluster that has gone through dozens of Ceph releases/upgrades.

I see a few options:

1. Do not buy new LRC hardware for POK.  Just use Proxmox storage for teuthology logs, etc. until Sepia LRC gear moves
2. Buy new LRC gear, migrate what’s necessary, integrate old Sepia gear into “new” LRC
3. Buy new LRC gear, have new modern LRC and run alongside old LRC

There is no scenario where we don’t move the existing LRC in my opinion.

Thoughts?
