Unfortunately, if you've removed your backup of the original file, the data is lost. If you still have a copy of the original file, you can remove the copy on the converted file system and replace it. The problem you're running into is that converting a file system to v3.6 from v3.5 allows *new* files to grow beyond the 2 GB limit, but not existing ones. The reason for this is that converting the file system only indicates that it has the ability to use files larger than that, but it doesn't update all the existing files. If you create a new file, it uses the newer metadata format that can describe much larger files. - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iD8DBQFFDsXvLPWxlyuTD7IRAheZAJ9hIwFztEGNgAu12XWunj42e7SYGACglca3 HQI+nvkGehJxOe9asRZweGg= =NUad -----END PGP SIGNATURE-----
