Hi! On http://e2fsprogs.sourceforge.net/ext2intro.html I found the strings "BSD-like synchronous updates" "it can cause corruption in the user data" . On http://www.mckusick.com/softdep/ I did not find such a statement. Are soft updates safe for user data? I do not really understand, what the first www page means... Maybe they mean, that the new file size (that would be meta data, I think) is written before the user data, so that the file contains undetermined data in its tail. I would be glad, if somebody tells me, if ufs with soft updates writes file size and block information after user data writes have been committed?
