While there is always a chance something like this can go wrong, you always keep backups right? Right? A while back I made a few patches to the ubuntu e2defrag to make it work properly on ext3 and stress tested it quite a bit on a small test filesystem with no issues, so using it SHOULD be fine. -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
