这取决于你的设置。首先检查仲裁大小：cat/etc/mesos master/quorum
比检查这个好http://mesos.apache.org/documentation/latest/operational-guide/
减少仲裁大小

The following steps indicate how to decrement the quorum size, using 5 -> 3 masters as an example (quorum size 3 -> 2):

Initially, 5 masters are running with --quorum=3
Remove 2 masters from the cluster, ensure they will not be restarted (see NOTE section above). Now 3 masters are running with --quorum=3
Restart the 3 masters with --quorum=2
To decrease the quorum by N, repeat this process to decrement the quorum size N times.

我认为这行不通。三个主机计数将允许一个主机失败，剩下的两个仍然可以找到法定人数。如果您只剩下一个主机，则无法达到法定人数。
