[Gluster-users] DNS resolution failure at boot

Fri Dec 4 16:57:20 UTC 2015

Ah, just tried it on some fresh machines. Looks like the solution that 
worked there isn’t making my cluster any happier. Any other thoughts?

(to be clear, looks like that was adding vdsmd-network.service as an 
After target, and vdsmd.service as a Before target)
