How to Resolve Index File Causing Search to Fail - Status Error -37

  • Last updated on

This article refers to the Barracuda ArchiveOne version 7.3 and higher.

If Searches from the ArchiveOne Admin console or from the ArchiveOneSearch website fail to complete, open the service trace and search for error -37. Error -37 is a General Error that indicates that one of the extended files is damaged in some way and cannot be read, causing the search to fail.

An individual masterfile refers to a number of extended index files, so further diagnostics are required to determine which individual extended file is causing the issue.

Resolve the Issue

To resolve this issue, use the following steps to enable the diagnostic partition mode on the Archive Server.

Complete the following steps on the Archive server:

  1. Browse to the Local Configuration Store in C:\ProgramData\Barracuda\ArchiveOne\LocalConfigurationStore
  2. Open the file Service.ini in a text editor such as Notepad.
  3. At the bottom of the file, add a new line: ArchiveSearchDiagnosticMode=1.
  4. Save and close the file.
  5. Open the Microsoft Services console (services.msc) and restart the ArchiveOne Service.  
  6. Re-run the search to reproduce the error and collect the latest log files. This allows you to identify the extended file that is causing the issue. Search for the line about to check partition file which precedes the -37 error. For example:

  8. Send a copy of the file in question to Barracuda Support to determine if the file can be repaired. If the file cannot be repaired, you must restore the file from backup.
  9. To revert the change, delete the ArchiveSearchDiagnosticMode line created in step 3 above from the service.ini, and then restart the ArchiveOne Service.
