We switched to running the voting LVM driver job from Ubuntu to CentOS because the "nfs-utils" package on Ubuntu 16.04 lacked two bug-fixes [1][2] required to test IPv6 exports. The kernel package has been updated on Ubuntu 18.04 [3] and the latest package has these fixes. Switching back to Ubuntu will also help us move faster towards our python3-first goal since there are no plans to support python3 in the CentOS base repositories.
