Answer

Run an Object Existence Check  to check consistency across all nodes
 
If there are missing objects errors will be seen on the results page

If the Object Existence Check comes back with no missing objects there is no data loss:

Additional Information

StorageGRID give the following message during a recovery:
 
"ATTENTION: Do not rebuild more than a single node within a 15 days period. Rebuilt two or more within 15 days of each other may result in data loss!"
 
There is no way to speed this process up. Rebuilding more nodes in this period risks data loss.
