In this talk we will highlight the operational challenges we faced while bringing up a high-throughput EOS instance for the Run 3 ALICE data acquisition. The journey started in 2020 and we are still perfecting the instance to this day. During this time all storage nodes got migrated from CentOS 7 to CentOS 8 and, later on, CentOS Stream 8, and not without inherent challenges which we are going to detail in this talk..
