Error message

requested to remove the mark, but file does not exist

What it means

RemoveMark found no marker file to remove — the requested mark (deletion/no-compact/no-downsample) does not exist on the block. This is a sentinel-condition message for idempotency/awareness, not a storage failure.

Solutions

1. Nothing to remove — verify the block ID and marker type
2. List block files to confirm current marks
