some information about this bug, as I tried again and the mount worked properly,


[root@Centos1 ~]# mount -t nfs -o vers=3,nolock 10.1.12.134:/dist-rep/d1 /mnt/nfs-test
[root@Centos1 ~]# cd /mnt/nfs-test
[root@Centos1 nfs-test]# ls
[root@Centos1 nfs-test]# touch a
[root@Centos1 nfs-test]# mkdir dir
[root@Centos1 nfs-test]# ls -l
total 20
-rw-r--r-- 1 root root    0 Sep 22 04:07 a
drwxr-xr-x 2 root root 8192 Sep 22 04:07 dir
[root@Centos1 nfs-test]# 
[root@Centos1 nfs-test]# 
[root@Centos1 nfs-test]# mkdir a
mkdir: cannot create directory `a': File exists
[root@Centos1 nfs-test]# ls
a  dir
[root@Centos1 nfs-test]#
