选项3：Email通知
如果Linux虚拟机不受VMware补丁的支持，你也不太愿意修改内核源的话，你至少应该配置虚拟机，以便发生问题时你能知道。一种方法是创建一个脚本，每10分钟运行一次或随你所选。下面是一个脚本例子：
#!/bin/bash
#
# use the first argument to this script as the
# email address to send notifications to
TO="$1"
#
# get the output from the mount command
#
MOUNT_OUT=`mount`
#
# see if the string 'ro' exists in the
# output of the mount command. be careful，
# if there is a CD-ROM inserted into the
# server this will always be true and you
# will get a lot of false positives
echo $MOUNT_OUT | grep \(ro\)
#
# get the return code for the grep
# operation.
#
RO=$？
#
# grep returns an exit code
# of 0 if there is a match
#
if [ "$RO" = "0" ]
then
#
# send an e-mail notification saying
# that there is a file-system that
# has been mounted as read-only
#
BODY=$MOUNT_OUT
echo read-only file systems found
echo $BODY
`which sendmail` -f root@`hostname --fqdn` -t << FooBar
From: root@`hostname --fqdn`
To: $TO
Subject: `hostname` has read-only file systems $BODY
FooBar
#
# exit with a status code of 1 if
# read-only file systems were found
#
exit 1
fi
#
# exit with a status code of 0 if no
# read-only file systems were found
#
exit 0
安装这个脚本，不要忘记给它一个邮箱地址。如果虚拟机的一个文件系统重启为只读时，它会提醒你，给你忽略这个问题的机会。记住，这个脚本假定你运行的是本地邮件服务器，不过也可以修改成通过中继主机发送邮件。
