If you encounter this issue again, let us know and will continue to investigate. Please note that we recommend running MongoDB with RAID-10.

It's a long time. DB size is 100GB. We use 20 threads CPU. And we have a large number of requests. For server status is constantly monitored. We use CentOS 7. thomas.schubert commented on Tue, 13 Dec 2016 18:38:03 +0000: Hi nexcode, This assertion failure generally indicates that some or all of the data files have become corrupt in some way. It's not clear if the corruption is in the index or the data itself, and in cases like this, it's very difficult to be confident that the corruption is isolated beyond the file level. To help us understand what's going on here, I've assembled a list of routine questions about data storage and the configuration of your environment. But, please understand that it is unlikely that we will be able to determine the root cause of this issue. What kind of underlying storage mechanism are you using? Are the storage devices attached locally or over the network? Are the disks SSDs or HDDs? What kind of RAID and/or volume management system are you using? Would you please check the integrity of your disks? Has the database always been running MongoDB 3.4.0? If not please describe the upgrade/downgrade cycles the database has been through. Have you manipulated (copied or moved) the underlying database files? If so, was mongod running? Preceding the corruption, were there any other server errors logged? Are you using journaling? What kinds of indexes do you have (TTL, etc)? Have you run out of disk space recently? To resolve this issue, I would recommend performing a initial sync, or starting mongod with --repair. Thank you, Thomas
