Under the collection folder, I had 5 wt files for my collection. For exemple, now I have collection-10-2456006026897874487.wt with 77MB and collection-10-4298854520594963500.wt with 2GB. And I can't access the data from collection-10-4298854520594963500.wt Even the collection "local" has this duplicated files. collection-0-2456006026897874487.wt and collection-0-4298854520594963500.wt On the server log, I found just a "SERVER RESTARTED" on the day that the new wt files were created. What can I do to recovery my data? |

Hello lgmaestrelli, Unfortunately, this behavior indicates that there was corruption on the disk, most often cause by a faulty storage layer. In this situation, our best recommendation would be to resync the affected node or restore from a backup if possible. To prevent this type of problem in the future please take note of the following guidelines to help mitigate any issues related to unreliable storage layers or server failures.
Thanks, |
