I hit upon a case where two files are getting tracked
thru the same object ids. My understanding is that
this is against the principle of object ids. Can
someone (NTFS team) confirm?
Basically I’m having a file with a object id and a
hardlink to it. When I delete the file, the objectid
starts tracking the hardlink, which is now the single
link to the file
When I recreate the file, the old object id tracks
this file too (bug?). Thus it seems to me that two
different files are now tracked thru the same object
ids.
Below are the steps to repro the issue, I have to add
that the same steps does not always lead to the issue.
I’m running XP Professional SP2.
