Answer 1

This is the first step of trouble shooting which i did but no success . as i said both copy catalog index is in failed status
What I have done
Create 
a full catalog index on mounted copy
Get Index catalog GetSearchIndexForDatabase.ps1 "databaseName"
Stop the index service and delete the catalog index by using ps1
.\ResetSearchIndex.ps1 -force "databaseName"
Start Search Index
crawling not initiated after this 
2. Delete the failed copy and re add it again which added successfully but reseed process getting failed with same error .. and event ID 245 Information Store (4492) :  The internal database
copy (for seeding or analysis purposes) has been stopped because it was halted by the client or because the connection with the client failed.
