Re: Explanation of NFS and other similar features/tools

Thanks all

It was a thought to simplify backups on multiple LPARs to a sandbox and
then have OPS backup all saves on one tape device with a minimum of disk
space required.

Having multiple tape devices is not always needed and restoring if needed
can be done the slower longer method transferring data back across LPARs.

Jim,

Let's leave off "that has the ability to be recovered from" since you
can't even use it to back up to.
This will remove the ambiguity of people wondering if you're trying to say
that you can't restore from it since it's awfully hard to do a bare metal
restore if you cannot access an NFS mount. Because if that was the only
concern it would be quite easy to dup from the virtual image catalog to
physical tape and then run that over.

Could it be used to map to another system, yes
Can it be used for backup that has the ability to be recovered from: no.

Interesting

Could it be used then to map a link to another system or LPAR.

Example
I would like to do SAVXxx commands to the other system from where I could
do
a centralized backup to tape.

Right now I have to save to the local IFS and then in a second step save
to
tape. Would this allow me to do it in 1 step?

Thanks

Darryl

There are two parts to NFS. The client, and the server.
If you're familiar with QNTC then you are aware that you can do a
WRKLNK '/QNTC/mypcserver/mypcshare' and look at shares on various
PC's. This would be a client.
You can also create a 'share' using IBM i Navigator that PC's can
access.
This would be a server.
Both QNTC and shares are comparable, but different, than NFS.
There are issues with QNTC that make some people tend to shy away from
it.

You use EXPORTFS (since EXPORT was already used in binder language) to
serve up a directory.
You use MOUNT from an IBM i client to consume what some server exported.

Other open systems, and even old proprietary legacy systems like
Windows, also support NFS as a client and a server.

Drawbacks: It's a little more setup. And learning the options of
EXPORTFS and MOUNT is a curve.
Pros: It works. Unlike QNTC to a system with numerous shares defined
that are multiple characters long, with many of the shares having the
first x number of characters identical.

I have always seen these but never had a need to use them or so I
thought.
I do not have a need right now.

What and how are these tools intended to be used?

Reading a current thread on the NFS, I got curious. To date I have
simply used the IFS root extensively.

TIA
