 |
|
I'm trying to create a network booting system and following the tutorial on the gentoo wiki.
For it to work correctly I have to have "Root file system on NFS" compiled into my kernel which is CONFIG_ROOT_NFS.
However this isn't in the options in menuconfig i just get the following in File System -> Network File System...
| Code: | <*> NFS file system support
[*] Provide NFSv3 client support
[ ] Provide NFSv4 client support (EXPERIMENTAL)
[ ] Allow direct I/O on NFS files (EXPERIMENTAL)
<M> NFS server support
[*] Provide NFSv3 server support
[ ] Provide NFSv4 server support (EXPERIMENTAL)
[*] Provide NFS server over TCP support
< > Secure RPC: Kerberos V mechanism (EXPERIMENTAL)
< > Secure RPC: SPKM3 mechanism (EXPERIMENTAL)
<M> SMB file system support (to mount Windows shares etc.)
[*] Use a default NLS (cp437) Default Remote NLS Option
< > CIFS support (advanced network filesystem for Samba, Window and other CIFS compliant servers)
< > NCP file system support (to mount NetWare volumes)
< > Coda file system support (advanced network fs)
< > Andrew File System support (AFS) (Experimental) |
if i search the .config file for CONFIG_ROOT_NFS it isn't in there...
I thought maybe it was now implied by one of the other options but when I boot I get...
| Code: |
VFS: Cannot open root device "nfs" or unknown-block(0,255)
Please append a correct "root=" boot option
Kernel panic- not syncing: VFS: Unable to mount root fs on unknown-block(0,255)
|
my grub line says....
| Code: |
kernel /test/boot/kernel-2.6.11-gentoo-r8 ip=dhcp root=/dev/nfs nfsroot=10.0.0.1:/diskless/test
|
Does anyone have any ideas?
Thanks in advance |

ok I've managed to get it to work...
thanks to MajikC in the following thread...
https://forums.gentoo.org/viewtopic-t-240592.html
basically I had to enable the following in my kernel... i think the latter items appeared after enabling the first...
Device Drivers --> Networking support ---> Networking options ---> IP: kernel level autoconfiguration
Device Drivers --> Networking support ---> Networking options ---> IP: DHCP Support
File Systems ---> Network File Systems ---> Root file system on NFS
Just posting this in case anyone has the same problem...
off to enjoy diskless goodness now! |
