ContentIndexState AutoSuspended for lagged copies

  • 아티클

Your Exchange 2016 lagged copies may stopped being indexed with ContentIndexState AutoSuspended after applying recent CU4
You may also see these events :
ID:       1009
Level:    Warning
Source: MSExchangeFastSearch
Message :
The indexing of mailbox database <mailboxdatabase> encountered an unexpected exception.
Error details: Microsoft.Exchange.Search.Core.Abstraction.OperationFailedException: The component operation has failed.
---> Microsoft.Exchange.Search.Core.Abstraction.CatalogReseedException:
The database 'guid (<mailboxdatabase>)' needs to be crawled but is not mounted on the preferred active server. Requesting a reseed.

--- End of inner exception stack trace ---

This is in fact expected behavior to Autosuspend lagged copies when possible.
This change allows to save network bandwidth by suspending such index which would likely not be used.

I would recommend to keep this normal behavior.
But if for some reason you require such database to be indexed , you can use this command to block this feature and index all databases as in CU1 :
New-SettingOverride -Name DisableSkipLagCopyForOnPrem2016 -Component Search -Section SkipLagCopy -Parameters @("Enabled=false") -Reason "Disable SkipLagCopy"

    We have this exact "issue" after updating Exchange 2016 servers from CU2 to CU4. I can't seem to find anything in the release notes or other blogs anywhere mentioning this. Is there a way to have Microsoft confirm this via a document or announcement?
