Server: CentOS 7
NFS root filesystem for client and Kernel: Slackware 14.1
I enabled "Root file system on NFS" and "IP: kernel level autoconfiguration" with "DHCP,BOOTP,RARP" support, recompiled the Kernel(3.10.17).
TFTP,NFS,DHCP all ready.
I ensure that NFS can be mounted by a linux client.(mount -t nfs ... )
DHCP and TFTP worked properly, and I can boot from an isolinux kernel use ram root filesystem.
Now, I need a diskless node so I need the kernel to mount a root filesystem via NFS.
kernel kernels/vmlinuz append ip=dhcp root=/dev/nfs nfsroot=192.168.1.4:/srv/diskless/slackware-14.1,nfsvers=3 raid=noautodetect
I get the error when boot
VFS: Unable to mount root fs via NFS, trying floppy.
Also, it seems the kernel didn't get an ipaddress by DHCP when boot.
(No information about displayed, ether I use "ip=192.168.1.7: ... :eth0" manually)
As the Slackware use huge-kernel, so I don't have an initrd image.(Problem may be here?)(My Computer's Linux didn't have ether, and works properly :) )
Or may be some option in kernel menuconfig I didn't select :( .(and I really need to know it)
