Hemant Kumar updated HDDS-11705:
--------------------------------
Description:
Ozone snapshot uses /volume/bucket path as a key prefix to traverse the key
space and generate snapshot diff. It also uses the same volume bucket path to
maintain a snapshot chain for garbage collection. Currently, Ozone snapshot
doesn’t resolve the linked bucket to the original bucket and creates a snapshot
and performs other snapshot operations on the linked bucket.
Since there is no key based on the linked volume bucket path in the original
bucket, SnapDiff returns an empty diff (no diff).
> Ozone snapshot returns empty diff for snapshots taken on linked bucket
