Is it changing block mapped inodes to extent mapped? Resising the inodes/GDT? Changing other things like growing large inode space for ns timestamps/version? We have an option to e2fsck (like -D for rehash directory, but instead "-E expand_extra_isize") to resize the "extra_isize" of an existing inode to ensure that enough space is in the filesystem for i_version_hi, if it isn't already. This is in our patch "e2fsprogs-expand-extra-isize.patch" in the Lustre patchset. I think it makes more sense to have options for existing tools, rather than having 10 new different tools, but maybe Ted has other opinions.
