More WPS Office Online Resize Required Kernel: Linux 2.
Only online volume expansion is supported at this time. The new volume size is reflected in the file system meta data where other nodes will pick it up.
Cluster aware flock 2 Required Kernel: Linux 2. File locks taken on one node from userspace will interact with those taken on other nodes. All flock 2 options are supported, including the kernels ability to cancel a lock request when an appropriate kill signal is recieved by the user.
Unfortunately, POSIX file locks, also known as lockf 3 or fcntl 2 locks are not yet supported in a cluster manner. We hope to have that ready in an upcoming version of Ocfs2. Userspace Clustering Required Kernel: Linux 2. These changes allowed the node to look to other nodes inode allocators for free space before giving up.
Locks taken on one node will interact with those taken on another node. Due to the group communication required to make these locks coherent, a userspace cluster is required. Extended Attributes Required Kernel: Linux 2. Small attributes can be stored directly in the inode block, which provides a large performance increase.
If no more attributes can fit in the inode block, new ones are stored externally in a name-indexed btree. Small attribute values are stored inline, near their meta data, while large attribute data grows out to a btree. In theory the btrees have similar limits to inode data. Amongst other benefits, this allows us to support large block devices with more than 32 bits worth of block numbers.
As a part of these patches, and 'inode64' mount option is added which toggles creation of inodes whose inode number requires more than 32 bits to be adequately described. The changes work with the existing set of quota tools though, you'll need support in ocfs2-tools to turn the file system feature on. We feel this feature is especially critical to a cluster file system, where our customers have repeatedly stated to us a desire to minimize the amount of total cluster downtime, even if it's the disk which corrupts.
Indexed Directories Required Kernel: Linux 2. Millions, even. Without this feature, the lookups are sequential which on modern hardware does not perform well over a few thousand files. With this feature, the file names are stored in a btree allowing the fs to quickly traverse to the block the could hold that file name.
Reflink unlimited inode-based writeable snapshots Required Kernel: Linux 2. These snapshots look like a hard link. In fact, the two share similar restrictions. Just like a hard link, one can only reflink regular files and the link has to be on the same file system as the source. But unlike a hard link, a reflinked file has the same data as the source only at the time of creation as all writes to either file results in a Copy-on-Write on that file.
Like a hard link and unlike symlinks , a reflinked file is indistinguishable from its source. There is no parent-child relationship. PMV is written in Python , an interpreted, object-oriented language that is easy to learn. PMV also offers an extremely useful 'Undo' command for most operations. ADT provides menus to:. VISION , or the Visual Programming Environment , is an advanced environment in which Python-based object-oriented components can be dragged-and-dropped and 'wired' together to create new applications.
It consists of various libraries of 'nodes', each node performing some well-defined computational task. Molecules can be read in, for example, using one of the 'MolKit' library's nodes.
