NFS no longer working ?

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?

Yep also installed nfs-utils 1.0.6.

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
