我正在尝试使用对mesos的持久卷支持,并且要让它工作起来非常困难。
我已按如下方式配置了每个从属服务器,并确认它们已使用此新配置成功重新启动:
/etc/mesos slave/资源
[
{
"name" : "disk",
"type" : "SCALAR",
"scalar" : { "value" : 4194304 },
"disk" : {
"source" : {
"type" : "PATH",
"path" : { "root" : "/mnt/disk1" }
}
}
},
{
"name" : "disk",
"type" : "SCALAR",
"scalar" : { "value" : 4194304 },
"disk" : {
"source" : {
"type" : "PATH",
"path" : { "root" : "/mnt/disk2" }
}
}
},
{
"name" : "disk",
"type" : "SCALAR",
"scalar" : { "value" : 4194304 },
"disk" : {
"source" : {
"type" : "PATH",
"path" : { "root" : "/mnt/disk3" }
}
}
},
{
"name" : "disk",
"type" : "SCALAR",
"scalar" : { "value" : 4194304 },
"disk" : {
"source" : {
"type" : "PATH",
"path" : { "root" : "/mnt/disk4" }
}
}
},
{
"name" : "disk",
"type" : "SCALAR",
"scalar" : { "value" : 4194304 },
"disk" : {
"source" : {
"type" : "PATH",
"path" : { "root" : "/mnt/disk5" }
}
}
},
{
"name" : "disk",
"type" : "SCALAR",
"scalar" : { "value" : 4194304 },
"disk" : {
"source" : {
"type" : "MOUNT",
"mount" : { "root" : "/mnt/disk6" }
}
}
},
{
"name" : "disk",
"type" : "SCALAR",
"scalar" : { "value" : 4194304 },
"disk" : {
"source" : {
"type" : "MOUNT",
"mount" : { "root" : "/mnt/disk7" }
}
}
}
]
具体来说,这表明我拥有无保留的资源。具体地说(这里有完整的回答):
{
...
"slaves": [{
"id": "c5e59876-5157-463f-b31e-16b34d6ffc72-S8",
"pid": "slave(1)@172.30.31.55:5051",
"hostname": "redacted47.redacted.com",
"registered_time": 1458810586.61153,
"resources": {
"cpus": 32,
"disk": 29360128,
"mem": 256651,
"ports": "[31000-32000]"
},
"used_resources": {
"cpus": 1,
"disk": 0,
"mem": 128,
"ports": "[31282-31282]"
},
"offered_resources": {
"cpus": 0,
"disk": 0,
"mem": 0
},
"reserved_resources": {},
"unreserved_resources": {
"cpus": 32,
"disk": 29360128,
"mem": 256651,
"ports": "[31000-32000]"
},
每当我尝试向它提交请求持久卷的作业时,所有从属服务器都会拒绝它,声称没有可用的磁盘资源:

如果我试图发布一个直接针对mesos主机创建卷的请求,那么它会拒绝该请求,并说“磁盘资源不足”,如下所示:
# curl -v -i \
-u "marathon:$(cat /etc/marathon/.secret)" \
-d slaveId=c5e59876-5157-463f-b31e-16b34d6ffc72-S8 \

"volume": {

}

我束手无策。我不知道我在做什么,我正在尽我最大的努力遵循文件。任何关于我可能做错了什么的暗示都将非常感激。
我在跑步:
中观 0.28.0
马拉松赛跑 1.0.0RC1
我将尽可能地遵循以下资源中的说明:
https://mesosphere.github.io/marathon/docs/persistent-volumes.html
http://mesos.apache.org/documentation/latest/persistent-volume/
http://mesos.apache.org/documentation/latest/multiple-disk/
谢谢你的阅读!

抱歉,我无法添加评论。
我觉得文件有点吓人。它是详细的,它很多,但我正在努力学习中观,马拉松等在我自己的时间,没有例子是真的很难为我。我更喜欢的是在一个页面上显示一个小集群,其中包含ip地址、磁盘、cpu以及设置主机、代理和zookeeper集合所需的配置文件。一些示例json文件展示了如何在特定用例中使用marathon。
我的目标是在我的公共github帐户中为自己做一些注解,显示我的测试集群,并解释在持久卷工作时如何配置所有内容,jenkins和私有docker注册表都在mesos中,但我离这还很远。

首先感谢你提供了这样一个很好的文件问题!
你的问题似乎是:
a) 没有可用的根磁盘资源。一旦您手动指定了磁盘资源,mesos将自动停止检测根磁盘。您可以简单地添加一个根磁盘资源,如本文所述,这将解决您的问题。
b) 上面的“createvolume”http请求将只考虑根磁盘资源(由于上面解释的原因,您没有根磁盘资源)。如果您想使用非根磁盘,您应该考虑这里非常简短地提到的source字段。
顺便说一句,任何关于如何改进文档的反馈都是受欢迎的(我将添加一个关于这个问题的简短说明,但是用户的任何反馈都是非常有用的)!请随意贡献!
希望这有帮助!
