| Description |

Hi, We run MongoDB 3.2.10 in an OpenShift cluster. Data for one of databases is stored on NFS share which run out of space resulting in data corruption. WiredTiger.turtle is empty and I'm unable to start the server or run automated recovery. I've heard about manual recovery options. Are they documented somewhere? Thanks, |

Hello pkar, Unfortunately, this error indicates that there was corruption on the disk. In this situation, my best recommendation would be to resync the affected node or restore from a backup if possible. Thanks, |

Hello pkar, Thank you for the report. If you can provide the WiredTiger.wt and WiredTiger.turtle files we can attempt a repair of the database, but please keep in mind that this is not a guaranteed fix. Thanks, |
