// Test resync command:
|
|
// 1. Start master/slave deployment.
|
|
// 2. Insert a document to seed the oplog.
|
|
// 3. Assert that the resync command fails when the slave is caught up to the master.
|
|
// 4. Stop the slave.
|
|
// 5. Insert enough documents to rotate the oplog.
|
|
// 6. Restart the slave.
|
|
// 7. Assert the resync command now works on the slave.
|
|
// 8. Assert the slave eventually has the same data.
|
|
// 9. Assert the slave now rejects the resync command.
|
|
//
|
|
// This test cannot be run on ephemeral storage engines, because after restarting, at step 6, the
|
|
// slave will not have any data and will start an initial sync, rejecting the resync command.
