Yesterday, I upgraded hcoop‘s openafs file and database servers from 1.4.10 to 1.6.7 (except for cantankerous old deleuze). Today I removed the 1.4.10 machine from afs service with no problems… and then rekeyed. With no problems.
On the one hand, no problems is great. On the other hand, it feels a bit anti-climactic after all of the work that led up to this moment. I think I deserve a beer.
