Post subject:  Problem with NFS support after kernel rebuild

Hi

First as a first time poster let me just say a huge thankyou to the Knoppmyth team. I'd been trying to get Myth running reliably on my Epia M10K for a month or so but kept hitting problems. After about an hour with the latest Knoppmyth CD I have a frontend running with hardware MPEG decoding and the Unichrome drivers without a hitch. Thank you so much :)

Now onto my problem ;)

Bouyed as I was by success I decided to go the whole hog and convert the box to net boot as had been my original intention for the Epia. (I have built net booting boxes in the past so am familiar with the requirements.)

I unpacked the kernel sources and rebuilt the kernel from the included config file making a couple of mods for netboot support. Basically I made NFS support builtin rather than a module and turned on Kernel level IP config.

I installed the new kernel and rebooted from the local disk to check all was well and it seemed OK until I tried to mount NFS filesystems from my backend / fileserver box:

Code:
root@azkaban:~# mount gryffindor:/share/media/movies /mnt/movies

mount: fs type nfs not supported by kernel


Here's what the .config says about NFS support :

Code:
root@azkaban:~# grep -i NFS /usr/src/linux/.config
CONFIG_NFS_FS=y
CONFIG_NFS_V3=y
# CONFIG_NFS_V4 is not set
# CONFIG_NFS_DIRECTIO is not set
CONFIG_NFSD=m
CONFIG_NFSD_V3=y
CONFIG_NFSD_V4=y
CONFIG_NFSD_TCP=y
CONFIG_ROOT_NFS=y
CONFIG_NCPFS_NFS_NS=y


I've tried specifying UDP, TCP and various NFS versions (I had V4 support enabled initially) all to no avail.

Does any one have any suggestions ? Any one successfully netbooting Knoppmyth ?

TIA

Paul

Odd error in the first place?! All I can say is I've verified it works with next release.

Ahem :oops:

OK I messed up. Being of a RHEL bent I'd forgotten all about needing to rerun lilo after installing a new kernel :oops: Needless to say that once I remembered and ran it everything works fine after a reboot.

Sorry for bothering you chaps :(
