trouble mounting nfs

[visionlogic]

Hi Everybody,

First off, I'd like to say hello and thank you to the other Gentoo users who help on this forum. I began learning Gentoo about 6 months ago, and have to say: I am thankful for the support already received indirectly by reading posts on here. This is my first post as a forum member, so wanted to start it off with gratitude.

Now, onto my issue. After days of searching, I havn't been able to find anything which leads to a solution. There have been other posts from users who had similar symptons, but realized that they needed to reboot, add nfs support in their kernel, install nfs-utils, etc.

I have done all these things but can't seem to figure it out. Every system file that I know to check seems to indicate the proper settings.

I am unable to mount a drive found on my NAS after adding kernel support for my AMD graphics card. It was working before, and I had the drive automatically mounting at boot by adding an appropriate fstab entry.

Once I updated the kernel, however, it stopped working.

To get to the bottom of the problem, I tried reverting the change. For some reason this didn't help. I actually tried starting from a fresh kernel config with make defconfig. After reconfiguring everything to minimally support what I need (including nfs and the amd card), I recompiled and installed the kernel. Heck, I even rebuilt world for good measure (this is my second gentoo device, and the system does not have much on it yet--in fact, I was configuring the graphics drivers as part of the bringup process)

Still, I am getting the same behavior. I can ssh into the NAS and view the files, but can't mount.

Here is a series of commands and their output to illustrate the problem. The order of connands is indicative of the things I have tried, and steps I have taken towards a solution. Does anybody know what else I can do to investigate/solve this problem?

After a bit more troubleshooting, I stumbled on the problem. Whenever I did the thing that broke nfs, it also broke vfat, which is the type of my boot partition. This meant that while I thought I was installing the newly compiled kernel, I was actually just installing to a directory called /boot within my rootfs. My kernel updates weren't actually taking place, even though everything else about the state of the system looked right.

What I did to fix it:
-chroot into the system after mounting everything properly from a systemrescuecd
-reinstall kernel after verifying that /boot was actually pointing to my boot partition

Hopefully this note can help somebody else solve a similar problem. On another note, the amd graphics drivers are still causing me trouble, but this is an issue for another thread.

Cheers
