-* UID/GID is shared from [[Cluster 2]] to [[Cluster 3]] but not strictly enforced.
+* disks from [[Cluster 2]] are exported read-only to [[Cluster 7]] during the transition from 2 to 7.
-* disks from [[Cluster 2]] are exported read-only to [[Cluster 7]] during the transition from 2 to 7.
-* We will experiment with SAMBA (yes, SAMBA) exports from cluster 2/7 to [[Cluster 8]] aka coreHPC.  Research only.
 * The DNS server for [[Cluster 2]] is subservient to the DNS server for [[Cluster 0]]. All other DNS servers have zero inter-dependencies.
-* 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.
-* Currently all www gateways are hosted on cluster 2.
-* We plan to establish a www server on cluster 7 and begin migrating services.
-* We are also investigating hosting some of our www traffic on cluster 8.
 No other exceptions known.
