A Disk Usage Alert Led Me Down the OpenStack Rabbit Hole
Since the issue had remained unresolved, I decided to take ownership of the investigation. Our existing disaster recovery setup consisted of two independent single-node OpenStack Swift deployments. Instead of native replication, data was periodically copied from the primary server to the backup server using a custom synchronization process, where objects were downloaded, staged on the backup server, and then uploaded back into its own Swift instance.
