Gargi Jaiswal updated HDDS-13666:
---------------------------------
Description:
Sorting based on density is ok to choose source and possible destination, but
the logic of choosing destination here can not be direct reverse loop, and need
care for above.
And if no destination is possible to choose, should mark disk as balanced.
This is reverse looping is especially seen in case of very low threshold such
that the volume utilisation of source and destination disk is close making
diskbalancer running forever without doing actual balancing.
