Review large MoH deployment testing Nouveau branch on prod data
How much spare disk space do they need?
Sugat concerned about more than 5x as seen in research ticket
Elijah: I’m in the process of procuring additional storage to begin the upgrade process and wanted to clarify that we settled on 5x current capacity e.g. one clone has a 5TB volume with 3.2TB utilization, should we expand to 16TB or up to 25TB to get some margin of safety.
recommendation: 16TB should be fine since the utilization is 3.2TB
Interrupted upgrades should both not lose all progress, and be able to resume where they left off
recommend starting in MoH Data Center with 8vCPU/16GB RAM to see how it goes. Success or failure will be well to inform TCO Squad with next steps.
Maybe if a 3.2TB instance needs >16TB (25TB!!?!), do we need to ship TCO V2 (eg in 4.2x) before TCO v1 (in 5.0) which will reduce total space needed
TCO Squad agrees that we should wait for Elijah’s testing in MoH datacenter, this may be weeks, possibly months in worst case, to completed. In the interim, upgrade disk space research can continue
