Implementing Off-line resizing is a bit tough task because it requires a user space library to read internal meta data of the nilfs file system and append updated blocks to it. This is almost equivalent to implementing kernel functions of nilfs in user land. So, we have no concrete schedule now. If you are using RHEL6 or its clones, however, standalone kernel modules supporting online-resizing are available from: http://www.nilfs.org/en/pkg_centos.html. For other Linux distros, the standalone kmod may be applicable with or without customizing the source code. it has a glue code to support multiple kernel versions. For reference, the source code of the standalone kmod is available at: git://github.com/nilfs-dev/nilfs2-kmod-centos6.git With regards, Ryusuke Konishi > -- > FSF associate member #7257 np.
