SCIDB_LE_DATABASE_HEADER_CORRUPTED


#1

Hi,
Our metatlas scidb instance won’t start up. After combing through the logs a bit, I found this error:

Is it possible to recover from this error? This a fairly large array, and recreating it will be very difficult. Any help you can provide would be greatly appreciated.

Thanks,
