Description
As milkie pointed out, it's possible for the writeConcern write in jstests/concurrency/fsm_libs/cluster.js to fail to run if a failover is occurring and there's no primary:
this.executeOnMongodNodes(function (db) {
|
// Execute on all primary nodes
|
if (db.isMaster().ismaster) {
|
// Insert a document with a writeConcern for all nodes in the replica set to
|
// ensure that all previous workload operations have completed on secondaries
|
var result = db.getSiblingDB('test').fsm_teardown.insert({ a: 1 }, wc);
|
assert.writeOK(result, 'teardown insert failed: ' + tojson(result));
|
assert(db.getSiblingDB('test').fsm_teardown.drop(), 'teardown drop failed');
|
}
|
});
|
We should fail with a clear error message if the branch is not executed at all (because of a transient lack of a primary).
