* This test is only for the WiredTiger storageEngine
|
|
* Test nojournal option with wiredTiger replset. This test will fail with mmap because
|
|
* unclean shutdowns are not safe. If running without a journal, WT starts up from last
|
|
* valid checkpoint, so should recover.
|
|
*
|
|
* Start a set.
|
|
* Insert data into collection foo
|
|
* fsync secondary member 1
|
|
* Kill -9 secondary member 1
|
|
* Add some more data in a new collection.
|
|
* Restart member 1.
|
|
* Check that it syncs from the last checkpoint and data is there.
