This task tracks copying the graphite data from labmon's current old disks to the new SSDs once they arrive (tracked in T137724). The process should be: 0. Notify labs-l mailing list and set topic on #wikimedia-labs IRC channel 1. Stop statsite/graphite/carbon-relay on labmon so it stops writing to the graphite data. Ensure and verify these are all stopped. 2. Rsync the data from `/srv/carbon/whisper` to the external HDD connected to the machine 3. Install SSDs 4. Re-install the operating system (Jessie) and re-provision the machine (with same role *and* hostname) 5. Stop the new statsite/graphite/carbon-relay on labmon so we don't start accepting new data yet 6. Clean out the new data we've accumulated in the short time between puppet starting the services and us stopping them 7. Rsync the data back 8. Make sure the data is owned appropriately by user `_graphite` and group `carbon-c-relay` 9. Start the services back up 10. Verify new data is coming in 11. PARTY!
