then it’s not finished yet or not started at all. You should have a start log line and finish log line for each filewalker and each satellite. They may work for several days.

2024-03-04T02:51:41Z    INFO    retain  Moved pieces to trash during retain     {"process": "storagenode", "Deleted pieces": 452481, "Failed to delete": 504, "Pieces failed to read": 0, "Pieces count": 11509460, "Satellite ID": "12EayRS2V1kEsWESU9QMRseFhdxYxKicsiFmxrsLZHeLUtdps3S", "Duration": "65h26m46.5101556s", "Retain Status": "enabled"}

“Duration”: “65h26m46.5101556s”
