Exchange 2010 keeps loosing indexing so we need to reindex mailbox databaeses RRS feed

  • Question

  • Hi All

    We have a problem with exchange 2010 (got all the updates and rolups) where now and then people loosing ability to search they emails (NOT a local issue, test-exchangesearch fails) and we have to re index mailbox databases by running ResetSearchIndex.ps1 .

    Can anybody point me in the right direction to find why it is happening - which logs do I need to search and what to look for etc. Maybe somebody had similar issue and managed to resolve it.

    Thanks

  • Hi,

    If the existing indexing is not getting repaired, you can try to recreate it as fresh. It seems reset index do not repair the index files.

  • Hi,

    What errors did you get when running test-exchangesearch? 

    We could try to manually rebuild the search index instead of running scripts. Here are the steps:

    1> Stop the Microsoft Exchange Search Indexer service. Run Stop-Service MSExchangeSearch if you are into Shell.
    2> Browse to where the database files are located on the disk. Along with the database file, you will see a folder with “CatalogData-random string” as its name. Delete this folder, which stores the corrupt index.
    3> Restart the Microsoft Exchange Search Indexer service. Run Start-Service MSExchangeSearch if you are into Shell.
    4> Give it a minute and a new folder will be created and a new index will be built.

    To find the issue cause:

    1. Please run the following command to get the database status:

    Get-MailboxDatabaseCopyStatus "<DBName>" | fl 

    2. Use the CI Troubleshooter. For details, see Exchange 2010 SP1: The Troubleshooters.

  • I can repair indexing with ResetSearchIndex.ps1, but it brakes again after a few days (usually after weekend) and I just cannot find what is causing it (no error in the eventlog)

  • A bit of an update - I have raised logging level and now see following warning in Apps events:

    Event ID 119

    Source: MSExchange Search Indexer

    A stagnation of events in the notification queue has been detected for database MBD02. The number of notifications waiting in queue for more than 1800 seconds are 212, starting from watermark 6107000 and ending at watermark 6107808. These are being added to retry list. The current age of last notification indexed is 18

    Googeled it but have not found much info
