Solve Content Index Issue:

Display list of databases with content index issues:
Get-MailboxDatabaseCopyStatus * | where {$_.ContentIndexState -eq "Failed"}

Fix databases with content index issues by re-seeding their content index (this will not re-seed the entire database which is good):
Get-MailboxDatabaseCopyStatus * | where {$_.ContentIndexState -eq "Failed"} | Update-MailboxDatabaseCopy -CatalogOnly


Check Again to make sure all DB’s show as healthy:
Get-MailboxDatabaseCopyStatus * | where {$_.ContentIndexState -eq "Failed"}

Alternatively, here is the command to simply reseed the content index of a specific DAG database:
Update-MailboxDatabaseCopy -Identity “Remote 02\PDXEX2” -CatalogOnly
