After restarting one of the servers in Exchange Server 2010 DAG you get this error message in the event log.
PM’ the Microsoft Exchange Information Store Database SERVCERNAME’ copy on this server experienced a corrupted search catalog
Consult the event log on the server for other “ExchangeStoreDb” and “MSExchange Search Indexer” events for more specific information about the failure. Reseeding the catalog is recommended via the ‘Update-MailboxDatabaseCopy’ task.
To fix the problem we need to update the Search Catalog by using the update-mailboxdatabasecopy –catalogonly cmdlet
Fix
Run the following cmdlet on the passive copy of the Database:
Update-MailboxDatabaseCopy -Identity “DB\PASSIVESERVER” -SourceServer ACTIVESERVER -CatalogOnly
