I believe that the journal is stored in the root of the filesystem as a regular file called .journal, at least in some circumstances (especially when converting ext2 -> ext3). In any case, if the filesystem is left in a consistent state (ie, unmounted cleanly), it can be mounted as ext2 by earlier kernels that have zero knowledge of ext3 without incident. Doing a search for 'mount ext3 as ext2' turned up <http://www.zip.com.au/~akpm/linux/ext3/ext3-usage.html>. -- Bill Jonas * bill@billjonas.com * http://www.billjonas.com/ Developer/SysAdmin for hire!
