Thanks! I did some additional testing, and this seems to be an NFS
read issue. Here's some more information: This seems to be an NFS read issue for files that have hard links. I have tested the following scenarios with these results: Local disk source to NFS archive = good NFS source to NFS archive = broken NFS source to local disk archive = broken How to reproduce with some examples: Create our folder with files that have hard links on an NFS mount. We will use this as our source for creating the archive. Copying /usr/bin from an image is a good one to test with.
