[SAC] OSGeo Ganeti Cluster

[Lance Albertson]

Hi there,

Just checking in on this again as I'd like to either 1) finish migrating
these systems to Chef+CentOS 7 or 2) decommission them.

What's the status of your migration? Keep in mind these machines have been
running with a degraded array for a while now.

Thanks-
