Subject Re: KVM支持FC-SAN吗?
Date Wed, 08 May 2013 11:33:58 GMT
我在搭建cluster时,遇到些问题
luci启动了,界面也起来了,但在创建cluster时,一直报相同的错误,换了好几个环境,都一样
下面是报的日志:
/usr/lib/python2.6/site-packages/tw/core/view.py:223: DeprecationWarning:

我有尝试通过写cluster.conf文件来直接创建集群
但也发现错误:
service cman  start
Starting cluster:
   Checking if cluster has been disabled at boot... [  OK  ]
   Checking Network Manager... [  OK  ]
   Global setup... [  OK  ]
   Loading kernel modules... [  OK  ]
   Mounting configfs... [  OK  ]
   Starting cman... [  OK  ]
   Waiting for quorum... Timed-out waiting for cluster
[FAILED]
我都按照网上的一些配置文档做的,但总感觉好像少了什么步骤,求指导。
iptables,selinux,networkmanage 都关了
