allows a user to list the contents of the AFS directory, examine the ACL associated with the directory and access subdirectories. Insert (i) allows a user to add new files or subdirectories to the directory. Delete (d) allows a user to remove files and subdirectories from the directory. Administer (a) allows a user to change the ACL for the ...
Distributed file systems in clouds such as GFS and HDFS rely on central or master servers or nodes (Master for GFS and NameNode for HDFS) to manage the metadata and the load balancing. The master rebalances replicas periodically: data must be moved from one DataNode/chunkserver to another if free space on the first server falls below a certain ...
Hierarchical Data Format (HDF) is a set of file formats (HDF4, HDF5) designed to store and organize large amounts of data.Originally developed at the U.S. National Center for Supercomputing Applications, it is supported by The HDF Group, a non-profit corporation whose mission is to ensure continued development of HDF5 technologies and the continued accessibility of data stored in HDF.
CP/M file system — Native filesystem used in the CP/M (Control Program for Microcomputers) operating system which was first released in 1974. DFS – Acorn's Disc filing system. DOS 3.x – Original floppy operating system and file system developed for the Apple II. Extent File System (EFS) – an older block filing system under IRIX.
Some researchers have made a functional and experimental analysis of several distributed file systems including HDFS, Ceph, Gluster, Lustre and old (1.6.x) version of MooseFS, although this document is from 2013 and a lot of information are outdated (e.g. MooseFS had no HA for Metadata Server at that time).

ext4 (fourth extended filesystem) is a journaling file system for Linux, developed as the successor to ext3.. ext4 was initially a series of backward-compatible extensions to ext3, many of them originally developed by Cluster File Systems for the Lustre file system between 2003 and 2006, meant to extend storage limits and add other performance improvements.

Does linear programming admit a strongly polynomial-time algorithm? (This is problem #9 in Smale's list of problems.) How many queries are required for envy-free cake-cutting? What is the algorithmic complexity of the minimum spanning tree problem? Equivalently, what is the decision tree complexity of the MST problem?
