Ceph启动失败： ImportError: No module named rados

Question

三台机器，每台兼任mds和osd，其中一台兼任mon，初始化成功（倒腾了一整天。。。）

然后启动的时候失败，信息如下。。。

# /etc/init.d/ceph -a start
=== mon.00 === 
Starting Ceph mon.00 on ceph00...already running

我是用ceph源码编译安装的，我用lsmod命令查看也确实没有rados模块，但是又查不到怎么安装rados模块。。

求助。。。

@oscfox @zetrov 搜的时候搜到你们的提问，看到你们搞定了，请问对我这问题有什么头绪吗。。

Answer 1

应该是ceph或者ceph-deploy的依赖装到了python2.6中，而系统用的是python2.7，求问怎么解决，除了直接用python2.6
