It should be perfectly safe to run e2image on a read-only mounted file system option, so it's not obvious to me why the force option would be needed in that case. Also, if we are saving a "normal" (not a raw or qcow) e2image file, we are only backing up the statically located metadata blocks (i.e., superblock, block group descriptors, inode table, and allocation bitmaps). If we do this on a mounted file system, the e2image file is less useful, but I'm not sure I'd call it completely useless. If the goal is to backup critical metadata, it will do that just fine. So maybe it's worthy of a warning, but I'm not sure it should require a force option. If the user is trying to capture a raw or qcow image file, I agree that requiring that the file systme either be mounted read-only, not mounted at all, or that a force option be specified, makes sense. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
