我在碎片化的Mongo集群的mongos实例上运行sh.status()命令,并且出现异常。
mongos> sh.status()
assert: command failed: {
"ok" : 0,
"errmsg" : "error processing query: ns=config.mongosTree: ping $gt new Date(1542173873192)\nSort: {}\nProj: {}\n No query solutions",
"code" : 2
} : aggregate failed

我正在ubuntu 16.04平台上运行Mongo 3.2。在ubuntu 14.04平台上的MongoDB 3.0版上运行正常。我已经重新安装了所有内容,并且也在新计算机上尝试了此操作,除了sh.status()命令之外,其他所有功能都正常运行。
谢谢。

这是因为我的mongo配置服务器中启用了notablescan属性。禁用notablescan
后,命令运行正常。您可以通过运行此命令来检查notablescan
的状态。
db.adminCommand( { getParameter: 1, notablescan: 1 } )
如果启用notablescan
,则输出如下所示。
{
"notablescan": true,
"ok": 1
}
