It seems like addshard treats hostnames case-sensitively, which is inconsistent with how hostnames work in DNS.
Here's my replica set, addshard failures below. (I know that using localhost adds some extra stupid to the problem, but I don't have a routable hostname to test with right now.)
> rs.conf()
{
"_id" : "a",
"version" : 3,
"members" : [
{
"_id" : 0,
"host" : "LOCALHOST:27017"
},
{
"_id" : 1,
"host" : "LOCALHOST:27018"
},
{
"_id" : 2,
"host" : "LOCALHOST:27019"
}
]
}
Here are a bunch of attempts to add it as a shard:
mongos> db.adminCommand({addShard:"a/localhost"})
{
"ok" : 0,
"errmsg" : "in seed list a/localhost, host localhost:27017 does not belong to replica set a"
}
mongos> db.adminCommand({addShard:"a/localhost:27017"})
{
"ok" : 0,
"errmsg" : "in seed list a/localhost:27017, host localhost:27017 does not belong to replica set a"
}
mongos> db.adminCommand({addShard:"a/localhost:27017,localhost:27018"})
{
"ok" : 0,
"errmsg" : "in seed list a/localhost:27017,localhost:27018, host localhost:27017 does not belong to replica set a"
}
mongos> db.adminCommand({addShard:"localhost:27017"})
{
"ok" : 0,
"errmsg" : "host is part of set: a use replica set url format <setname>/<server1>,<server2>,...."
}
mongos> db.adminCommand({addShard:"LOCALHOST:27017"})
{
"ok" : 0,
"errmsg" : "can't use localhost as a shard since all shards need to communicate. either use all shards and configdbs in localhost or all in actual IPs host: LOCALHOST:27017 isLocalHost:0"
}
