Hi Tigran,
I guess that's one way ( a dark white box way, which still needs to be
looked into)... but I was more thinking of a more high level built in
user method (e.g module option ,or mount option)
We used to have it but it was removed, being pointless. 4.1 means pNFS.
The optional clause in the STD means client need no implement it but since
we slaved so hard to do implement it we see no point ever disabling it.
As an administrator policy it is best controlled in a single place at the
Server. Instead of having a crap option set at every client. What does that
give you?
If the admin wants to let you have a choice, for what ever reason that I
can't currently imagine, He can setup two exports of the same FS one
with the pnfs option, one without.
I don't think you can export the same FS ( same path ) twice in 2
different ways...
In any case, I understand the explanation above concerning the design.
just tried to check if this line of thinking (4.1 without pNFS) is
needed and/or /wanted.
Thanks,
Lior K.
The point of the all pNFS support is that everything is automatic, Server
upgraded/extended/scaled boom transparently works.
NACK on any user visible disables. It's a maintenance disaster. If you
do find any real bugs with the pNFS option left on, please report ASAP
and we'll fix it
Cheers

Thanks for the fast response,

Hi Lior,
you can blacklist the layout driver in /etc/modprobe.d/nfsv41.conf
blacklist nfs_layout_nfsv41_files

Hi Trond,
The rfc 5661 states that pNFS is an optional feature.
Is there currently an intent to implement some sort of an option (module
option ,or mount option) to run the NFSv4.1 client without pNFS
functionality?
Thanks,
Lior K.
