mongodb 副本集失败

[程序猿与代码]

两台电脑做测试
zhf-linux:192.168.0.11
zhf-maple：192.168.0.12
在192.168.0.12上启动
启动命令：mongod --dbpath /home/zhf/node0 --replSet rs0
在192.168.0.11上启动
启动命令：mongod --dbpath /home/zhf/node1 --replSet rs0

在192.168.0.12上进入数据库,执行如下命令
> use admin
switched to db admin
> conf={_id:"rs0",members:[{_id:0,host:"zhf-maple:27017"},{_id:1,host:"zhf-linux:27017"}]}
{
"_id" : "rs0",
"members" : [
{
"_id" : 0,
"host" : "zhf-maple:27017"
},
{
"_id" : 1,
"host" : "zhf-linux:27017"
}
]
}
> rs.initiate(conf)
{ "ok" : 1 }
rs0:SECONDARY> rs.conf()
{
"_id" : "rs0",
"version" : 1,
"protocolVersion" : NumberLong(1),
"members" : [
{
"_id" : 0,
"host" : "zhf-maple:27017",
"arbiterOnly" : false,
"buildIndexes" : true,
"hidden" : false,
"priority" : 1,
"tags" : {

},
"slaveDelay" : NumberLong(0),
"votes" : 1
},
{
"_id" : 1,
"host" : "zhf-linux:27017",
"arbiterOnly" : false,
"buildIndexes" : true,
"hidden" : false,
"priority" : 1,
"tags" : {

},
"slaveDelay" : NumberLong(0),
"votes" : 1
}
],
"settings" : {
"chainingAllowed" : true,
"heartbeatIntervalMillis" : 2000,
"heartbeatTimeoutSecs" : 10,
"electionTimeoutMillis" : 10000,
"catchUpTimeoutMillis" : 60000,
"getLastErrorModes" : {

},
"getLastErrorDefaults" : {
"w" : 1,
"wtimeout" : 0
},
"replicaSetId" : ObjectId("5a5b4512be0049ae009cd493")
}
}
但是一直无法同步：提示如下消息

好的，我用三台机器试下

because I cannot see a majority

副本集至少三台，或者三个进程

增加了一台电脑：192.168.0.4 ubuntu 启动后有2台是正常的。但是192.168.0.12这台启动的时候报如下的错误。然后就自动退出了 2018-01-16T17:46:25.127+0800 E REPL [replication-0] Initial sync attempt failed -- attempts left: 1 cause: CommandNotFound: error while getting last oplog entry for begin timestamp: no such cmd: find 2018-01-16T17:46:26.127+0800 I REPL [replication-1] Starting initial sync (attempt 10 of 10) 2018-01-16T17:46:26.978+0800 I REPL [replication-1] sync source candidate: ubuntu:27017 2018-01-16T17:46:26.995+0800 I STORAGE [replication-1] dropAllDatabasesExceptLocal 1 2018-01-16T17:46:26.995+0800 I REPL [replication-1] ****** 2018-01-16T17:46:26.995+0800 I REPL [replication-1] creating replication oplog of size: 33904MB... 2018-01-16T17:46:27.079+0800 I STORAGE [replication-1] WiredTigerRecordStoreThread local.oplog.rs already started 2018-01-16T17:46:27.079+0800 I STORAGE [replication-1] The size storer reports that the oplog contains 0 records totaling to 0 bytes 2018-01-16T17:46:27.079+0800 I STORAGE [replication-1] Scanning the oplog to determine where to place markers for truncation 2018-01-16T17:46:27.247+0800 I REPL [replication-1] ****** 2018-01-16T17:46:27.261+0800 I REPL [replication-1] Initial sync attempt finishing up. 2018-01-16T17:46:27.261+0800 I REPL [replication-1] Initial Sync Attempt Statistics: { failedInitialSyncAttempts: 9, maxFailedInitialSyncAttempts: 10, initialSyncStart: new Date(1516095963274), initialSyncAttempts: [ { durationMillis: 0, status: "CommandNotFound: error while getting last oplog entry for begin timestamp: no such cmd: find", syncSource: "ubuntu:27017" }, { durationMillis: 0, status: "CommandNotFound: error while getting last oplog entry for begin timestamp: no such cmd: find", syncSource: "zhf-linux:27017" }, { durationMillis: 0, status: "CommandNotFound: error while getting last oplog entry for begin timestamp: no such cmd: find", syncSource: "zhf-linux:27017" }, { durationMillis: 0, status: "CommandNotFound: error while getting last oplog entry for begin timestamp: no such cmd: find", syncSource: "zhf-linux:27017" }, { durationMillis: 0, status: "CommandNotFound: error while getting last oplog entry for begin timestamp: no such cmd: find", syncSource: "zhf-linux:27017" }, { durationMillis: 0, status: "CommandNotFound: error while getting last oplog entry for begin timestamp: no such cmd: find", syncSource: "zhf-linux:27017" }, { durationMillis: 0, status: "CommandNotFound: error while getting last oplog entry for begin timestamp: no such cmd: find", syncSource: "zhf-linux:27017" }, { durationMillis: 0, status: "CommandNotFound: error while getting last oplog entry for begin timestamp: no such cmd: find", syncSource: "ubuntu:27017" }, { durationMillis: 0, status: "CommandNotFound: error while getting last oplog entry for begin timestamp: no such cmd: find", syncSource: "ubuntu:27017" } ] } 2018-01-16T17:46:27.261+0800 E REPL [replication-1] Initial sync attempt failed -- attempts left: 0 cause: CommandNotFound: error while getting last oplog entry for begin timestamp: no such cmd: find 2018-01-16T17:46:27.261+0800 F REPL [replication-1] The maximum number of retries have been exhausted for initial sync. 2018-01-16T17:46:27.292+0800 E REPL [replication-1] Initial sync failed, shutting down now.

有谁知道原因的么，帮看下这个是什么失败呢
