I have 2 exchange 2013 servers with 4 DBs each, exch one has 2 active mounted and 2 passive healthy.

This morning I found that all 4 DBs are mounted on ExServer2, the 4 DBs on ExServer1 are healthy but their Content index state is unknown.

1. I could active the 2 DBs back to ExServer1, I get an error about the content index state that is unknown
2. Suspend/Resume did do anything
3. Suspend/Update stated movind file and I the end I get an error:

warning
Seeding of content index catalog for database 'DB4' failed. Please verify that the Microsoft Search (Exchange) and the Host Controller service for Exchange services are running and try the operation again. Error: Could not connect to net.tcp://localhost:3863/Management/SeedingAgent-6BCDDF4B-88E9-47CE-8EB6-836714D1AE9912/Single. The connection attempt lasted for a time span of 00:00:02.0313113. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:3863. .

 

Checked: all services are running.

1) Try restarting the FAST Search Service (MS Exchange Search service)
2) If this does not work, recreate the catalog file (e.g: content index)

- Stop the MSExchange Search service
- In the location of the database find the content index files (it should be a separate folder with the words like CatalogData-blahblahblah)
- Remove that folder (recommend moving it somewhere else
- Start the search service, and wait for the folder to get recreated (takes about 10 -15 minutes)

Nothing worked, I even removed the DB copy, deleted the folders, added the copy and the same thing.

Got this error
error
DB4
The seeding operation failed. Error: An error occurred while running prerequisite checks. Error: The specified database isn't configured for replication and therefore cannot be used to perform seed operations

Do me a favor, run Get-MailboxDatabase "DB Name" | Get-MailboxDatabaseCopyStatus please and post it here. Also run the following command, as I think this could be replication network related:

Get-DatabaseAvailabilityGroupNetwork | FL

Restart both Search Service, but on the passive node. I thought you were doing it on the active node.

Go to control panel
Click on Adminstration tools
Click on Local Security Policy
Under Security Settings/Local Policies/Security Options
Make sure that "System cryptography: Use FIPS compliant algorithms for encryption..." is disabled

This is what fixed my issue, hope you have the same problem
