Total blob size: 0

You may encounter an INFO[0014] Total blob size: 0 error message during migration with copy mode. This indicates that the storage is empty or that blob storage mapping is defined incorrectly. The error may result in a panic message in versions prior to MMT 2.0.2-GA.

To resolve the issue, ensure that the correct source volume is specified in the mount parameter of the MMT command line. Note that the exact source storage name may vary.

--mount source=dtr-registry-nfs-000000000003,target=/storage

If the issue is not resolved, update to MMT 2.0.2-GA or later.
