hi ! I am newbe pl help me.
while login from diskless node on tftp getting message as bellow:
kernel panic - not syncing : No init found. Try passing init= option to kernel.
where & how to pass init= to kernel ?
Thanks in advance

hi there

tftp looks fine
there is some problem wit the kernel u are using of with ur configuration

do u have the Filesystem support that u are using in ur kernel

regards

first you should read the howto-s about root over nfs, boot howto, and diskless howto ( i think there are 2). second... read them again.

but overall the procedure is:
1. configure dhcp or bootp on the server. test.
2. configure nfs on the server. test.
3. make the client installation. tar.
4. export the common directories for the clients ( /tftpboot/rootfs/home, /tftpboot/rootfs/usr, /tftpboot/rootfs/opt ). test
5. make directories for every client ( /tftpboot/clients/101, /tftpboot/clients/102 ... so on ). test
6. compile a kernel with root over nfs _and_ with the driver for the network adapter. test.
7. use mknbi on the kernel.
8. use syslinux and a floppy disk. test. test. test.
9. use tftp server to export the kernel image and get rid of the floppy disk.
10. celebrate.

cheers

P.S.
your particular error I got when the loaded kernel could not mount the root directory. which means root over nfs in the kernel OR invalid parameters for the kernel itself

thnks for reply
i have done every thing mentioned by you. but as if i am using RHEK 4 Beta where i can't compile kernel. I am using tftp server & on client side using PXEboot, so i am not using floppy or cd for booting the node. & my nodea are diskfree. but i think loaded kernel could not mount the root direcotry. but wht to do now ?
thnks in advance.

what is the Filesystem of ur root

also have u tried using LTSP(ltsp.org)

regards

ext3 is root's filesystem.

did u compile the kernel urself??


regards

no i can't. because i am using RHEL 4 Beta which will not allowed you to compile kernel.

i have to confess that i don't have any idea what RHEL 4Beta is...
... but if i can imagine the things right you are going throught this:

the tftp works - you got your kernel downloaded.
it starts to boot and it comes to the point of mounting the root.
could you write down your client's /etc/fstab?
... on the client is there any indication that the network interface is up?
