After much tries. problem sovled.:-) It's a authentication problem. |
2 |
according to nfs mannual page: |
3 |
In addition to combining these sideband protocols with the main NFS |
4 |
protocol, NFS version 4 introduces more advanced |
5 |
forms of access control, authentication, and in-transit data |
6 |
protection. The NFS version 4 specification mandates |
7 |
NFSv4 ACLs, RPCGSS authentication, and RPCGSS security flavors that |
8 |
provide per-RPC integrity checking and encryption. |
9 |
Because NFS version 4 combines the function of the sideband |
10 |
protocols into the main NFS protocol, the new security fea\ |
11 |
tures apply to all NFS version 4 operations including mounting, file |
12 |
locking, and so on. RPCGSS authentication can |
13 |
also be used with NFS versions 2 and 3, but does not protect their |
14 |
sideband protocols. |

and this patch: |
17 |
https://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.4-rc2/2.6.4-rc2-mm1/broken-out/nfs-simplify-config-options.patch |

nfsv4 need DES and MD5.but in official kernel, the dependency missed, nor |
20 |
writes"you should say yes to support nfsv4", so I turn it down.(bad habbit). |
21 |
|
22 |
The patch is for 2.6.4, and I wonder why the dependency mistake still |
23 |
existed. Anyway, probleam solved. |
