mongo5.0.4   redhat 8

操作步骤：

MongoDB Enterprise mongos> var session = db.getMongo().startSession()
MongoDB Enterprise mongos> session.startTransaction()
MongoDB Enterprise mongos> var tb1 = session.getDatabase('testdb01').getCollection('table01')
MongoDB Enterprise mongos> tb1.updateOne({id:1},{$set:{"id":"88888"}},{multi:false})

{ "acknowledged" : true, "matchedCount" : 1, "modifiedCount" : 1 }

MongoDB Enterprise mongos> session.commitTransaction()
uncaught exception: Error: command failed: {
"ok" : 0,
"errmsg" : "Transaction was aborted :: caused by :: from shard rs_shard03 :: caused by :: 'prepareTransaction' is not supported for replica sets with arbiters",

},
"operationTime" : Timestamp(1647248380, 3),

} with original command request: {

} on connection: connection to 127.0.0.1:32017 :

然后mongos上find,currentOp等操作都无响应了。
