NFS no longer working ?

NFS no longer working ?

[Martin Ziegler]

Hi All,

just installed kernel version 2.6.7 on RedHat 8.0. Unfortunately i'm no 
longer able to use NFS. Are there any recent issues ? For a detailed 
problem description please see below. Any help is appreciated.

Thanks

  Martin


I have two machines..let's say A and B. On A / /boot and /sys are exported 
via /etc/exports. Machine B are mouting these sources when booting via NFS. 
Since i updated the kernel i get the following errors when machine A is 
starting the NFS services :

---
Jul 8 09:30:13 hostA exportfs: hostB:/boot: No such device
Jul 8 09:30:13 hostA exportfs: hostB:/sys: No such device
Jul 8 09:30:13 hosta exportfs: hostB:/: No such device
Jul 8 09:30:13 hostA nfs: Starting NFS services: succeeded
Jul 8 09:30:13 hostA nfs: rpc.rquotad startup succeeded
Jul 8 09:30:13 hostA nfsd[6376]: nfssvc: No such device
Jul 8 09:30:13 hosta nfs: rpc.nfsd startup failed
Jul 8 09:30:13 hostA nfs: rpc.mountd startup succeeded

----

cat /etc/exports:

/ hostB(ro,sync,no_root_squash) /sys hostB(ro,sync,no_root_squash) /boot 
hostB(ro,sync,no_root_squash)

----

cat /etc/hosts.allow

ALL:hostB

With the old kernel 2.4.20-8 i had no problems.

NFS support is compiled into the new kernel.

Did you update nfs-utils to the minimum required as detailed in 
Documentation/Changes?

I also had problems with NFS on 2.6.x (not the same as yours, though).
The solution was to do "mount -t nfsd none /proc/fs/nfsd" on the
server. You might wanna give that a try, maybe it'll help.

Eric,

it's mentioned in Documentation/Changes. When i try to mount i get the 
message "mount: fs type nfsd not supported by kernel" although NFS is 
compiled into the kernel. Perhaps there is another option which have to be 
enabled but i just overseen it ?

Thanks

  Martin

Do you have CONFIG_NFSD set?

[Martin Ziegler]

Whew...i was sure that i compiled NFSD into the kernel. When looking at 
.config i recognized that it was set to be compiled as a module. That was 
the trick. Sorry for that and thanks for your help!
