I've installed MongoDB V3 64bit RC8 and am getting the following error "2015-02-11T07:25:20.865+1100 I STORAGE [initandlisten] exception in initAndListen: 18656 Cannot start server with an unknown storage engine: wiredtiger, for the cmdline: |

nevf, can you please send the link for the white paper you mention? That will help routing the issue to the right people. As for your question, one can't "convert" a MMAPv1 instance to a WiredTiger one. Stand-alone instances are "converted" via dump and restore, and replica sets can be upgraded one node at a time. For more information please see the development release notes for 3.0.0, in particular the upgrade recommendations and checklists. |

Ramon, thanks for the quick response. I copied this from the MongoDB Whitepaper PDF I downloaded. It would be prudent to update that document. Can you point me at Docs for converting a MMAP DB to WiredTiger? Now I get: "2015-02-11T07:51:08.249+1100 I STORAGE [initandlisten] exception in initAndListen: 28574 Cannot start server. Detected data files in c:/webapps/database |

nevf, starting with 3.0.0-rc6 we normalized the storage engine name to "wiredTiger", please fix the capitalization in your command line. See Regards, |
