nfs正常，所有vm都能正常使用。
界面无法看到主存储
登入mysql,发现
storage_pool只有一条数据，理论上应该有管理节点+计算节点的合计记录数。
mysql>use cloud;
mysql> select * from storage_pool;

估计是那个地方发猫疯了（真没找到原因，估计是哪个地方卡死了，没法更新。）
可参考下这个的解决办法，
但我按他的方法打标记后，主存储是找到了，但所有系统出问题，连主机都找不到了。
幸好先做了备份，最终还是还原mysql的时候意外解决（所以论备份的重要性啊~~~~~~~）。
Linux下MySQL的备份与还原
备份
[root@localhost ~]# cd /var/lib/mysql (进入到MySQL库目录，根据自己的MySQL的安装情况调整目录)
[root@localhost mysql]# mysqldump -u root -p cloud>cloud.sql，输入密码即可。
还原
[root@localhost ~]# cd /var/lib/mysql (进入到MySQL库目录，根据自己的MySQL的安装情况调整目录)
[root@localhost mysql]# mysql -u root -p cloud
重启，
service cloudstack-management restart
正常。
mysql> use cloud;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
