I am trying to setup a diskless client which will mount over nfs to the server. When I try to boot the client I get the following error message:
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)
I've set up my kernel parameters as follows:
kernel=22.214.171.124:/linuxboot,192.168.100.14 <-- tftpboot parameters....(which works)
Linux PPC load: root=/dev/nfs rw nfsroot=126.96.36.199:/diskless/client01 ip=dhcp
The kernel is found via tftpboot, so I know the 'kernel' parameter above works. The kernel is loaded and start executing, but hits the above error eventually.
The mount point is properly exported from the server, as I can mount it manually from other machines.
I've read several threads about this topic (at least very similar), but none, as far as I've seen so far, has addressed mounting a nfs drive. I've only seen topics talking about local hard drives.
Any ideas,guidance is very appreciated...thanks...
