1、启动时出现的错误

  1. [root@znix ~]#/etc/init.d/nfs start
  2. Shutting down NFS daemon:                                 [  OK  ]
  3. Shutting down NFS mountd:                                  [  OK  ]
  4. Shutting down NFS services:                                 [  OK  ]
  5. Shutting down RPC idmapd:                                  [  OK  ]
  6. Starting NFS services:                                           [  OK  ]
  7. Starting NFS mountd: rpc.mountd: svc_tli_create: could not open connection for udp6
  8. rpc.mountd: svc_tli_create: could not open connection for tcp6
  9. rpc.mountd: svc_tli_create: could not open connection for udp6
  10. rpc.mountd: svc_tli_create: could not open connection for tcp6
  11. rpc.mountd: svc_tli_create: could not open connection for udp6
  12. rpc.mountd: svc_tli_create: could not open connection for tcp6
  13.                                                                           [  OK  ]
  14. Starting NFS daemon: rpc.nfsd: address family inet6 not supported by protocol TCP
  15.                                                                  [  OK  ]
  16. Starting RPC idmapd:                                         [  OK  ]

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。

2、【解决办法】编辑netconfig配置文件，注释相关TCP/UDP6的信息条目

  1. [root@znix ~]#vim /etc/netconfig
  3. #
  4. # Entries consist of:
  5. #
  6. #       <network_id> <semantics> <flags> <protofamily> <protoname> \
  7. #               <device> <nametoaddr_libs>
  8. #
  9. # The <device> and <nametoaddr_libs> fields are always empty in this
  10. # implementation.
  11. #
  12. udp        tpi_clts      v     inet     udp     -       -
  13. tcp        tpi_cots_ord  v     inet     tcp     -       -
  14. #udp6       tpi_clts      v     inet6    udp     -       -
  15. #tcp6       tpi_cots_ord  v     inet6    tcp     -       -
  16. rawip      tpi_raw       -     inet      -      -       -
  17. "/etc/netconfig" 19L, 769C written

3、重启服务验证

  1. [root@znix ~]#/etc/init.d/nfs restart 
  2. Shutting down NFS daemon:                                  [  OK  ]
  3. Shutting down NFS mountd:                                  [  OK  ]
  4. Shutting down NFS services:                                 [  OK  ]
  5. Shutting down RPC idmapd:                                   [  OK  ]
  6. Starting NFS services:                                           [  OK  ]
  7. Starting NFS mountd:                                           [  OK  ]
  8. Starting NFS daemon:                                          [  OK  ]
  9. Starting RPC idmapd:                                           [  OK  ]
