Siyao Meng updated HDDS-13452:
------------------------------
    Description: 
Any snapshot defragmentation write operation can only happen after OM upgrade 
is finalized.

----

Note: *Snapshot Defragmentation* was previously called *Snapshot Compaction* 
during development and in the design doc. It is renamed because the *Snapshot 
Compaction* name can be easily confused with *[RocksDB 
Compaction|https://github.com/facebook/rocksdb/wiki/Compaction]*, which is a 
different concept.
