- In the Domain/OS NFS 4.1 release notes it recommends against mounting
- the network root (//) for performance reasons. It stands to reason
- also.. Lets look at the following scenario:
-
- You have two Apollo nodes; //A and //B as well as an HP-UX node "H".
-
- H mounts A:// as /apollo.
-
- H accesses a file on /apollo/B.
-
- The file request goes to node A through NFS and then gets translated
- to a DDS page-request to node B. Node B supplies the page to node A
- via DDS and Node A transfers the data to node H via NFS.
-
- Therefore, all remote file accesses from Apollo nodes to HP-UX
- nodes will go through node A. This is an unnecessary link which
- will affect performance.
-
- A better solution is to install NFS on all of your Domain nodes
- (with the transition from NFS2.3 to NFS4.1, a 2.3 license translates
- to a 4.1 site license) and use the Automounter under HP-UX. Then when
- a file request for a file on Node B is queued, the Automounter will
- mount node B to wherever (presumably /apollo/B) and perform the
- request.
-
- : file, send a signal to 'init' to re-read /etc/ttys, and you have dialup
- : using the standard Unix 'getty' process.
-
- Preferably "kill -1 1" rather than something like "kill -9 1"... :-)
