If you download the ext2resize program from SourceForge, it has a program called "ext2resize" which will do this. Neither Stephen when he was integrating on-line resizing for Fedora/Red Hat Enterprise Linux, nor I when considering how to integrate this functionality into e2fsprogs, were comfortable with the code base enough to accept responsibility for maintaining it in its current form, which is why that functionality has not yet appeared in either RHEL4 nor in e2fsprogs. That being said, I'm not aware of anyone who has lost data or any other serious bugs in the ext2prepare program in ext2resize, aside from the fact that it has portability problems on big-endian systems. (One of ext2resize's problems is that it doesn't use libext2fs, but rather rolled its own library functions, which clearly was never tested on big-endian systems but which also has application-level functionality folded into its library routines, making a port to libext2fs more difficult than it ought to have been.) In any case, since requesting on-line resizing is now integrated into resize2fs, the only missing functionality only found in ext2resze is the ext2prepare progam to reserve space on an already-created ext3 filesystem. Adding this support is on my todo list, but to be honest other development items for e2fsprogs are higher priority at the moment. If someone wants to try writing an ext2prepare-like program using libext2fs, let me know, and I can give you an outline of what needs to be done. - Ted _______________________________________________ Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
