Database ContentIndex State: FailedAndSuspended in DAG

I have two exchange 2013 SP1 servers in DAG Exch01 and Exch02.

when I checked database copy status, it is showing contentindex state failed all four databases on both two servers. 

I tried with command "Get-MailboxDatabaseCopyStatus * | where {$_.ContentIndexState -eq "FailedAndSuspended"} | Update-MailboxDatabaseCopy -CatalogOnly" but this didn't helped.

I have tried to delete the index folders and reseed, also tried reseeding complete mailbox with no luck. 

Restarting server didn't helped as well.
