I upgraded Mongo Shard from 3.4 to 3.6 and trying to enable this:
mongos> db.adminCommand( \{ setFeatureCompatibilityVersion: "3.6" } );
{
"ok" : 0,
"errmsg" : "Could not find host matching read preference \{ mode: \"primary\" } for set shard2",
"code" : 133,
"codeName" : "FailedToSatisfyReadPreference"
}
mongos>
Now FeatureCompatibilityVersion: "3.6" is set on Config and shard.
configReplSet:SECONDARY> db.adminCommand( \{ getParameter: 1, featureCompatibilityVersion: 1});
{
"featureCompatibilityVersion" : {
"version" : "3.4",
"targetVersion" : "3.6"
},
"ok" : 1,
"$gleStats" : {
"lastOpTime" : Timestamp(0, 0),
"electionId" : ObjectId("000000000000000000000000")
}
}
configReplSet:SECONDARY>
shard1:SECONDARY> db.adminCommand( \{ getParameter: 1, featureCompatibilityVersion: 1})
{
"featureCompatibilityVersion" : {
"version" : "3.6"
},
"ok" : 1,
"$gleStats" : {
"lastOpTime" : Timestamp(0, 0),
"electionId" : ObjectId("000000000000000000000000")
},
"$configServerState" : {
"opTime" : {
"ts" : Timestamp(1556145038, 2),
"t" : NumberLong(7)
}
}
}
shard1:SECONDARY>
Now try to bounce mongos server and face this error:
