ubuntu-12.04 – Riak“错误”：“insufficient_vnodes

我们有4个节点Riak安装.它们运行在Ubuntu 12.04 LTS Precise安装的服务器上.
我们在2012年8月1日安装了1.1.4,并在可用时升级了1.2.0.

服务器名称是：

f1 – 10.10.0.12 – 这是第一个安装的服务器.我们已将其他人加入此服务器.这也服务于Riak控制.
s2 – 10.10.0.22 –
s3 – 10.10.0.23 –
s4 – 10.10.0.24 – 该服务器还提供Riak控制.

今天早上我们在应用程序日志中看到“可用节点不足”错误并重新启动所有节点.其中3个可用,除了“f1”

UPDATE : while I prepare this message live 3 nodes became unavailable
and need restart Riak.

wolfiem@f01:~$sudo /etc/init.d/riak start
Riak Failed to start within 15 seconds,see the output of 'riak console' for more information.
If you want to wait longer,set the environment variable
WAIT_FOR_ERLANG to the number of seconds to wait.

我试过将WAIT_FOR_ERLANG值设置为60秒,但我不能.

在vm.args中添加此行不起作用：

-env WAIT_FOR_ERLANG 60

我也尝试从终端设置它,但它也没有用.

wolfiem@f01:~$export WAIT_FOR_ERLANG=60

它仍然说“Riak未能在15秒内启动”

这是console.log输出：

这是error.log输出

这是crash.log输出：

您可以在下面找到riak控制台输出：

它表示带有原因错误的0邻居退出是由于(至少部分)运行的riak实例,它位于某个端口或其他资源上.

对我来说,这是一个运行的epmd实例,我用ps ax | grep riak找到它.杀了之后,问题就消失了.
