These are exceptions to the "each cluster is separate" rule.

disks from Cluster 2 are exported read-only to Cluster 7 during the transition from 2 to 7.
The DNS server for Cluster 2 is subservient to the DNS server for Cluster 0. All other DNS servers have zero inter-dependencies.

No other exceptions known.

-* UID/GID is shared from [[Cluster 2]] to [[Cluster 3]] but not strictly enforced.

-* we will experiment with nfs exports from cluster 2/7 to [[Cluster 8]] aka coreHPC.  Research only.
-* we tried nfs export from [[Cluster 2]] to [[Cluster 3]] shared/wynton. This was a disaster. Jobs running on wynton overloaded our nfs servers and made them unusable. This will probably happen when we export to cluster 8, but it is worth a try.
 No other exceptions known.
