Would you please double check? If there is no other corruption, I would expect the repair operation to rebuild the indexes. Thanks, Kelsey palak007 commented on Wed, 28 Feb 2018 05:27:46 +0000: Hi Kelsey T Schubert, mongod is running on other path but not only on /var/lib/mongodb. there is index-.wt files are missing in above path. But my question is how can i recover these index-.wt files in given path? your given solution is work for me. Log for mongod --repair is in previously attached file log.txt. Thanks. Palak Patel thomas.schubert commented on Wed, 28 Feb 2018 05:19:02 +0000: Hi palak007, Have you had any luck running mongod --repair with the new files? Would you show the output of that process if not? Thank you, Kelsey palak007 commented on Tue, 27 Feb 2018 05:12:36 +0000: Hi Kelsey T Schubert, Thanks for your solution. after replacing your files there is no more block header checksum. But there is another issue might here. I have found in log which is attached in log.txt file. There is missing all of index-1-2111875094627348415.wt files in /var/lib/mongodb. I log.txt s there any solution for this? Thanks! Palak Patel thomas.schubert commented on Mon, 26 Feb 2018 15:19:45 +0000: Hi palak007, I've attached a repair attempt of the files you provided. Please extract these files and replace them in your $dbpath and let us know if it resolves the issue. If you are still seeing errors after replacing these files, please provide the complete logs from the affected node so that we can further investigate. Thank you, Kelsey palak007 commented on Mon, 26 Feb 2018 09:45:05 +0000: Hi Kelsey T Schubert, Is there any updates on previous conversation? do you require anything else to check which way to solve issue? – Palak Patel, Thanks. palak007 commented on Mon, 26 Feb 2018 06:09:49 +0000: Hi Kelsey T Schubert, Yes sure.. i have uploaded WiredTiger.turtle too. please look into it. Thanks! Palak thomas.schubert commented on Mon, 26 Feb 2018 05:52:40 +0000: Hi palak007, So we can attempt to repair these files, would you please upload the wiredtiger.turtle file as well? Thank you, Kelsey
