%SECTION0{name=LinuxRootFilesystemUsingNFSVersion3}% Using NFSv3 for NFS Root Filesystem Question:: My NFS server only allows the protocol in version 3. Even though my kernel has "NFS client support for NFS version 3" compiled in, I cannot use this as a root filesystem. The boot process stops like this: <verbatim> Looking up port of RPC 100003/2 on 10.0.0.136 Looking up port of RPC 100005/1 on 10.0.0.136 Root-NFS: Server returned error -22 while mounting /opt/eldk/ppc_6xx VFS: Unable to mount root fs via NFS, trying floppy. VFS: Cannot open root device "nfs" or unknown-block(2,0) </verbatim> Answer:: In addition to the kernel support, you need to specify the "nfsvers=3" option to use NFS protocol version 3 as a rootfilesystem. So include something like the following in your kernel commandline: <verbatim> nfsroot=[<server-ip>:]<root-dir>,nfsvers=3 </verbatim>
