Dear list, |
| 2 |
|
| 3 |
I posted this on gentoo forums but maybe you guys could help me out as |
| 4 |
well. So I wanted to play around with building my own diskless node. |
| 5 |
Yes, I know there are easier ways to do this. Automated tools like |
| 6 |
Caos Linux, etc. etc. Anyway, I wanted to use gentoo and learn from |
| 7 |
the ground up. So I booted a box via pxe, tftp and dhcp. it boots--- |
| 8 |
but can't seem to find NFS. |
| 9 |
|
| 10 |
And yes, i've googled. none have worked. I don't know what I'm missing. |
| 11 |
|
| 12 |
I get this: |
| 13 |
|
| 14 |
rpcbind: server 192.168.2.1 not responding, timed out |
| 15 |
Root-NFS: Unable to get nfsd port number from server, using default |
| 16 |
Looking up port of RPC 100005/1 on 192.168.2.1 |
| 17 |
rpcbind: server 192.168.2.1 not responding, timed out |
| 18 |
Root-NFS: Unable to get mountd port number from server, using default |
| 19 |
Root-NFS: Server returned error -5 while mounting /diskless/192.168.2.11 |
| 20 |
VFS: Unable to mount root fs via NFS, tryi9ng floppy. |
| 21 |
VFS: Cannot open root device "nfs" or unknown-block(2,0) |
| 22 |
Kernel Panic - not syncing: VFS unable to mount root fs on unknown- |
| 23 |
block(2,0) |
| 24 |
|
| 25 |
Both client and server have root nfs turned on it their respective |
| 26 |
kernel. |
| 27 |
|
| 28 |
i have turned off the firewall on the server and still get the same |
| 29 |
error. |
| 30 |
|
| 31 |
pxelinux.cfg is this: |
| 32 |
|
| 33 |
DEFAULT /kernel8 |
| 34 |
APPEND root=/dev/nfs rw nfsroot=192.168.2.1:/diskless/192.168.2.11 |

I also tried this: i used the same cable and attached it to my mac and |
| 314 |
mounted /diskless/192.168.2.11 nfs share which points to the diskless' |
| 315 |
client's root. i was able to mount it. So i know nfs works. And yes i |
| 316 |
made sure to turn off the mac's wireless... so only ethernet was |
| 317 |
plugged in. |
