Rishabh Patel updated HDDS-14859:
---------------------------------
    Description: 
In the volume scanner, we open the RocksDb that is present on each volume. 
There could be transient errors when opening this RocksDb in readonly mode.
The volume scanner should therefore try to open the RocksDb as a secondary 
instance. 

  was:
In the volume scanner, we open the RocksDb that is present on each volume. 
There could be transient errors when opening this RocksDb in readonly mode.

The volume scanner should therefore try to open the RocksDb instance, a second 
time after a gap, to reduce any false positives when declaring disk failures.


> Use RocksDb secondary instance for validating volumes
