请教一个关于openfiler(iscsi-target)的2个iscsi-initiator发起方挂载share volume之后写数据的同步问题(vmware环境)！

网络结构：
   --------
|storage |
   --------
            |                   |
----------                      ----------
|webserver1| |webserver2|
----------                      ----------
软件介绍：
storage:
  OS: Openfiler-2.2-x86(2.2.r1166-1-1)
  Kernel: 2.6.19.4-0.1
  Vmware: 5.5.2-build.29772
  IP：192.168.3.13

webserver1,webserver2:
  OS: RHEL4U2
  Kernel: 2.6.9-22.EL
  iscsi-initiator: iscsi-initiator-utils-4.0.3.0-2(系统自带)
  Vmware：5.5.2-build.29772
  IP：192.168.3.201(webserver1), 192.168.3.202(webserver2)

配置如下，当把openfiler、webserver1(2)都启动之后：
一、storage server(openfiler)配置:
  1、/etc/ietd.conf文件
[root@openfiler ~]# cat /etc/ietd.conf
Target iqn.2006-01.com.openfiler:vg_data.lv_data1
        Lun 0 Path=/dev/vg_data/lv_data1,Type=fileio
Target iqn.2006-01.com.openfiler:vg_data.lv_data2
         Lun 0 Path=/dev/vg_data/lv_data2,Type=fileio
  2、/etc/hosts文件：
[root@openfiler ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1             linux40 localhost.localdomain localhost
192.168.3.202 webserver2.test.local webserver2
192.168.3.201 webserver1.test.local webserver1
192.168.3.13 openfiler.test.local openfiler test.local
  3、lvdisplay输出：
[root@openfiler ~]# lvdisplay
   --- Logical volume ---
   LV Name             /dev/vg_data/lv_data1
   VG Name             vg_data
   LV UUID             Q1GfQv-kQS0-JsxF-8aUP-GuLr-iaQZ-HxsFYu
   LV Write Access       read/write
   LV Status             available
   # open                1
   LV Size             320.00 MB
   Current LE          10
   Segments             1
   Allocation          inherit
   Read ahead sectors    0
   Block device          253:0

   --- Logical volume ---
   LV Name             /dev/vg_data/lv_data2
   VG Name             vg_data
   LV UUID             4FI80j-2zMa-zHF0-s5vk-yoN0-ygQI-Y31Q90
   LV Write Access       read/write
   LV Status             available
   # open                1
   LV Size             320.00 MB
   Current LE          10
   Segments             1
   Allocation          inherit
   Read ahead sectors    0
   Block device          253:1

二、Webserver1和2的配置：
  1、/etc/iscsi.conf文件：
[root@webserver1 ~]# grep -v "^#" /etc/iscsi.conf
DiscoveryAddress=192.168.3.13:3260

  2、/etc/hosts文件：
[root@webserver1 ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1             linux40 localhost.localdomain localhost
192.168.3.202 webserver2.test.local webserver2
192.168.3.201 webserver1.test.local webserver1
192.168.3.13 openfiler.test.local openfiler test.local

  3、/etc/fstab文件关于iscsi-initiator对iscsi-target的share-volume挂载：
[root@webserver1 ~]# cat /etc/fstab
/dev/sdc1             /media/lv_data2       ext3 defaults  0 0
/dev/sdb1             /media/lv_data1       ext3 defaults  0 0

  4、iscsi-ls -l输出：
[root@webserver2 ~]# iscsi-ls -l

  5、df和mount输出：
[root@webserver1 ~]# df

[root@webserver2 ~]# mount

/dev/sdc1 on /media/lv_data2 type ext3 (rw,sync)
/dev/sdb1 on /media/lv_data1 type ext3 (rw,sync)

问题：
当把openfiler、webserver1(2)都启动之后，openfiler(iscsi-target)的openfiler服务一切正常，webserver1(2)的iscsi服务也一切正常，挂载的数据都可以正常访问。
当我在webserver1上的/media/lv_data1或/media/lv_data2上创建一个new文件后，在webserver2上始终看不到，除非重新启动挂载方可。请问为什么？我看到有人说是vmware的问题，果真如此？是什么原因导致vmware无法做到同步？
