[Help] nfs client size cache test fail problem

["Su Yanjun <suyj.fnst@xxxxxxxxxxxxxx>" <suyj.fnst@xxxxxxxxxxxxxx>]

Hi Folks,

I'm getting this error when running nfstest.

Our OS:
[root@client1 test]# uname -a
Linux client1 3.10.0-957.el7.x86_64 #1 SMP Thu Oct 4 20:48:51 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Our test command line:

[test@client1 test]$  ./nfstest_cache --nfsversion=4  -e  /nfsroot --server 192.168.102.143 --client 192.168.102.142 --runtest acregmax_data

*** Verify consistency of data caching with NFSv4 on a file acregmin = 10 acregmax = 20
    TEST: Running test 'acregmax_data'
FAIL: File data should have not changed at t=0 FAIL: File data should 
have not changed just before acregmax PASS: File data should have 
changed just after acregmax


    PASS: File data should have not changed just before acregmin
FAIL: File data should have changed just after acregmin
    TIME: 1m1.911090s

5 tests (2 passed, 3 failed)

Any suggestion?
