If you run the below, its your query but modified slightly, run it now, then wait for 10 - 15 mins and run it again, if the IndexSeqNo does not change then you know nothing is getting Indexed for this Volume.

If the ISN is not changing, do a DS against the TransactionID for the very first item and see if it dumps successfully.
