Description Forgotten User js_DutmDZD 2006-02-15 04:34:32 UTC

This looks very much like bug #128784 but I have the latest (YOU) updates of both kernel and nfs* (and everything else) on both sides.
I don't see any errors in any logs, just a notice that the server doesn't do TCP and it falls back to udp (no clue why).
Both the server and client is Suse 10.0 x86_64 with nfs mounted /home.
Any time some application (like gconfd or evolution) tries to take a lock on a file it gets permission denied. Searching for the problem I found a few with similar problem but no resolution (since starting nfslock isn't possible).
It seems to be on the server side that the problem is because the same directory mounted from a Mandrake 10.1 server does not have the same problem.

Comment 1 Forgotten User js_DutmDZD 2006-02-15 15:19:43 UTC

I was running nfs-server-2.2beta51-212.2.x86_64.rpm on the server. After changing to nfs-server-2.2beta51-212.x86_64.rpm it started to work.
Given that the server package is a beta I guess this is more of a bug report on the beta51.

Comment 2 Olaf Kirch 2006-02-16 15:39:08 UTC

Please do not use the old user space nfs server.
Uninstall the nfs-server package and install nfs-utils instead.

Neil, could you track this please?

Comment 3 Forgotten User js_DutmDZD 2006-02-16 19:38:03 UTC

As you can see I already done the swap but you could add some info about it.

When I installed the server I knew it was going to be a nfs server so I selected the nfs-server package and when I selected nfs-utils it just told me about a conflict so I guessed that nfs-server was a superset of nfs-utils and the package description wasn't that much help in the choice (userspace vs kernel space, I have no clue on what is better or never).

Comment 4 Neil Brown 2006-02-23 06:17:31 UTC

There are a few things I don't understand:

1/ What "swap" have you done?

2/ In comment #1 you say you were running X and after changing to X it started to work.  That is the same X.  I don't understand.

Just to clarify.  You DO NOT want nfs-server installed.  You DO want nfs-utils installed.

Is your main issues that you would like the descriptions of these packages to be clearer, it is there something else?

Comment 5 Forgotten User js_DutmDZD 2006-03-07 18:39:59 UTC

Sorry, I should have read my own writing
I ment to say that I swapped from nfs-server-2.2beta51-212.2.x86_64.rpm to nfs-utils-1.0.7-13.x86_64.rpm so I already done that swap and after that it started to work again.

What I'm missing is more doc on one vs the other. You write that I don't want to run nfs-server, why not? if never, why is it even around?
I had expected that "rpm -qi" would give some hints on why I should use one over the other, so yes, I want the description to be clearer.

Comment 6 Neil Brown 2006-03-09 03:58:53 UTC

I'm reassigning this to Petr, the maintainer of the SuSE nfs-server package.  The suggesting is that the description should be clarified so that people don't install it accidentally.

nfs-server is an nfs server that runs in user-space.  As such it is a lot slower than the in-kernel nfs server, and does not comply as well the the standards for required behaviour.

I believe it is around because it has one or two features that some people want and that are not (and never will be) supported by the in-kernel server.  However that is just a guess. (It can do obscure things like following symlinks on the server instead of the client).

Comment 7 Petr Ostadal 2006-03-09 10:29:36 UTC

I appended following text to nfs-server description:
"Userspace NFS server is a lot slower than the kernel NFS server, but has some special features which are not in the kernel NFS server."
