Sorry, we have already cleaned that cluster, we need to keep providing service.

But I'm pretty sure the latter `bad split' has overwritten the
former's metadata entry, Based on what I remember:

select StartRow from METADATA where row >= '3:116.217.49.1' display_timestamps;
??? 3:116.217.49.1  StartRow 116.217.49.1
??? 3:116.217.49.1  StartRow 116.217.10.39
