启动NFS时提示消息如下：# service nfs startStarting NFS services: [ OK ]Starting NFS quotas: [ OK ]Starting NFS mountd: rpc.mountd: svc_tli_create: could not open connection for udp6rpc.mountd: svc_tli_create: could not open connection for tcp6rpc.mountd: svc_tli_create: could not open connection for udp6rpc.mountd: svc_tli_create: could not open connection for tcp6rpc.mountd: svc_tli_create: could not open connection for udp6rpc.mountd: svc_tli_create: could not open connection for tcp6 [ OK ]Starting NFS daemon: rpc.nfsd: address family inet6 not supported by protocol TCP [ OK ]Starting RPC idmapd: 根据启动提示可以获知，inet6地址族不被支持，原因是当前主机没有加载ipv6的模块，可以重新加载一遍ipv6模块解决这个问题。由于我的系统不需要ipv6的支持，所以还可以通过下面的操作，取消NFS的ipv6调用。
编辑netconfig配置文件，注释相关TCP/UDP6的信息条目。# vim /etc/netconfig# The network configuration file.
