Then you can simply point symbolic links to new character special file and restore your database system or move chunks through dd command from one disk partition to another (of course after OnLine shutdown). The symbolic links or hard links should always be used in all chunk names! If you don`t have links in chunk names, then the safest way to move chunks is to onunload or dbexport all your databases, reinitialize OnLine instance and reload your data back. The fastest and unsafest way is to shutdown OnLine, move chunks to final space and patch reserved pages with new chunk names and start OnLine again; I don`t recommend it. In all cases do level 0 archive first.
