2023-10-24T08:04:06.090+0000 7f7911f4b440 -1 datascan.scan_links: Unexpected error reading dentry 0x100003ff439/f1.log: (2) No such file or directory

file names sanitized.

The f1.log dentry was removed and then used for updating nlinks.

The error crash caused remaining metadata to not be updated. That should be avoided if necessary in addition to fixing the logic error.
