// Test SERVER-623 - starting slave from a new snapshot
//
// This test requires persistence because it assumes copying the dbpath with copy the data between
// nodes. There should not be any data in the dbpath for ephemeral storage engines, so this will not
// work. It also requires the fsync command to enduce replication lag.
// @tags: [requires_persistence, requires_fsync]
