Question

Exchange 2016 with 2 MailBox servers having status of Content index 'Failed' on all DBs , the server is member of 2 nodes DAG.
Unable to activate the DB on server having failed status.

tried all the possible options related to repair the failed content index in DAG.

Answer 1

Hi,
Is the index broken on one server or all servers?
If only one server affected, run "Get-MailboxDatabaseCopyStatus * | Where {$_.ContentIndexState -eq "Failed"} | Update-MailboxDatabaseCopy -CatalogOnly" to have a fix.

Can you run the following command and post the result:

Get-MailboxDatabaseCopyStatus -Server EX1| fl  

What Event is generated in Event Log? You might meet EventID 1010, then follow this KB and see if method 2 works: https://support.microsoft.com/en-us/topic/event-id-1010-is-logged-when-no-results-are-returned-during-a-search-on-a-server-that-is-running-exchange-server-2013-9f79b4a7-5d65-cdc7-98fb-34f6640b6c98
