Hi All,
For a while now I was under the impression that nfsd provided with Redhat
was the be all and end all, today after we had some fcntl locking issues it
appears thats not the case.
My first question is knfsd the same as the nfsd included in the nfs-utils package?
Secondly If its not how do I go about using knfsd over the stock nfsd?
Sorry for these basic questions but the total lack of information online
is quite shocking.
Cheers
Dave

Hmm, knfsd consists of 2 parts, the kernel nfsd-module and nfs-utils rpc.nfsd.
So the answer should be yes.

Bernd,
This is why I am getting confused, because I have seen papers
comparing userspace nfsd with knfsd - performance and feature wise.
Also some people are making reference to a knfsd process which
i dont have, even though i have the appropriate options turned on
in the kernel.
Yes i have see the howto and there is no reference to knfsd, which
is why i am getting confused - perhaps the was once a knfsd but now it
is merged with the other nfsd?
Cheers
Dave

Why do you want to compare unfsd and knfsd ? Just believe me, unless you have
very special conditions, you won't want to try unfsd.
Furthermore those papers should be rather outdated since except the ClusterNFS
users (we belong to them) nobody uses unfsd nowadays.

Running 'ps ax' knfsd should appear like this:
637 ? SW 569:03 [nfsd]
Whereas unfsd (in our case ClusterNFS) would appear as:
522 ? S 14:39 [rpc.nfsd.cnfs]
Or are you the 'Debian User' who doesn't manage to get knfsd running ? Without
further information from his log-files nobody will we able to help him in any
case.

The hole howto is about knfsd ;)

Check the HOWTO and FAQ (see http://nfs.sourceforge.net/). Common NFS
locking problems are discussed there.

No. knfsd is the generic name for the kernel NFS daemons. They reside
in kernel space. The nfsd and exportfs that included in the nfs-utils
package are just user controls for those daemons.

man nfsd

The NFS FAQ and HOWTO are both run by volunteers. If you think they
are incomplete, then feel free to offer to help write better ones.
Feel free too to browse the archives of this mailing list...
Cheers,
Trond

Bernd, Trond,
No not interesting in unfsd :)
Yes my nfsd shows up as [nfsd]. - i didn't occur to me that the "[]" meant
kernel :)
We have nfs working fine, but like i said reading some doco online
made reference to nfsd as well as knfsd. This doco is about 3 years old
however
so maybe the too have mereged since then.
In fact the html docs included in nfs-utils-0.3.3 package (redhat) make
reference
to a userspace and kernel space nfsd, with performance specs as well :)
I dont mean to put anyone down or anything, i think the nfs team are doing
a great job - i understand that its all volunteer work :)
I will read up on file locking - but this whole knfsd naming issue caught me
off guard :)
Cheers again
Dave
