- Start with a 3 node replica set in which all nodes are wiredTiger with journaling disabled
- Make a single write
- Attempt to step down the primary
When attempting the step down command you will get:
backup_test:PRIMARY> rs.stepDown()
{
"ok" : 0,
"errmsg" : "No electable secondaries caught up as of 2016-11-20T21:56:10.466+0000. Please use {force: true} to force node to step down.",
"code" : 50,
"codeName" : "ExceededTimeLimit"
}
The rs.status() looks as below. Not that all the optimeDurable are undefined:
backup_test:PRIMARY> rs.status()

Here are the command line options for a member. If I enable journaling, this problem disappears.
backup_test:PRIMARY> db.runCommand({getCmdLineOpts:1})
