Description
Two types:
1 Non-0th data objects who have no 0th object
2 0th data objects that were not tagged in the latest forward scrub pass.
On reflection, we probably don't need to do case 2 here, because we already have the ability to inject those files as lost+found. This is good, because otherwise case 2 would be extremely dangerous (any failure to tag in the forward scrub would result in deletion). So probably just implement case 1: iterate over all non-0th objects, check if the 0th object for that inode exists, if it doesn't, remove this object. Emit lots of warnings and require some kind of --i-am-sure flag!
