PA, IA In todays service oriented IT zero downtime becomes more and more a most wanted feature. If you want to change actions for single packages, right-click a package in the package view and choose an action. When debugging a problem, you sometimes need to temporarily install a lot of -debuginfo packages which give you more information about running processes. If you are only reading the release notes of the current release, you could miss important changes. However, this can be changed through macro configuration. In this case, the oldest zswap pages are written back to disk-based swap. YaST snapshots are labeled as zypp y2base in the Description column ; Zypper snapshots are labeled zypp zypper. Global variables, or environment variables, can be accessed in all shells. If it is 0 zero the command was successful, everything else marks an error which is specific to the command. The installation medium must be inserted in the HMC. Maintaining netgroup data. This option fetches changes in repositories, but keeps the disabled repositories in the same state—disabled. The rollback snapshots are therefore automatically deleted when the set number of snapshots is reached. The visible physical entity, as it is typically mounted to a motherboard or an equivalent.

AFS - a Secure Distributed File System
SLAC-PUB-11152 Part III: AFS - A Secure Distributed File System Alf Wachsmann Submitted to Linux Journal issue #132/April 2005 Stanford Linear Accelerator Center, Stanford University, Stanford, CA 94309 Work supported by Department of Energy contract DE–AC02–76SF00515. SLAC-PUB-11152.txt Part III: AFS - A Secure Distributed File System III.1 Introduction AFS is a secure distributed global file system providing location independence, scalability and transparent migration capabilities for data. AFS works across a multitude of Unix and non-Unix operating systems and is used at many large sites in production for many years. AFS still provides unique features that are not available with other distributed file systems even though AFS is almost 20 years old. This age might make it less appealing to some but with IBM making AFS available as open-source in 2000, new interest in use and development was sparked. When talking about AFS, people often mention other file systems as potential alternatives. Coda (http://www.coda.cs.cmu.edu/) with its disconnected mode will always be a research project and never have production quality. Intermezzo (http://www.inter-mezzo.org/) is now in the Linux kernel but not available for any other operating systems. NFSv4 (http://www.nfsv4.org/) which picked up many ideas from AFS and Coda is not mature enough yet to be used in serious production mode. This article presents the rich features of AFS and invites readers to play with it. III.2 Features and Benefits of AFS AFS client software is available for many Unix flavors: HP, Compaq, IBM, SUN, SGI, Linux. -
Linux Kernal II 9.1 Architecture
Page 1 of 7 Linux Kernal II 9.1 Architecture: The Linux kernel is a Unix-like operating system kernel used by a variety of operating systems based on it, which are usually in the form of Linux distributions. The Linux kernel is a prominent example of free and open source software. Programming language The Linux kernel is written in the version of the C programming language supported by GCC (which has introduced a number of extensions and changes to standard C), together with a number of short sections of code written in the assembly language (in GCC's "AT&T-style" syntax) of the target architecture. Because of the extensions to C it supports, GCC was for a long time the only compiler capable of correctly building the Linux kernel. Compiler compatibility GCC is the default compiler for the Linux kernel source. In 2004, Intel claimed to have modified the kernel so that its C compiler also was capable of compiling it. There was another such reported success in 2009 with a modified 2.6.22 version of the kernel. Since 2010, effort has been underway to build the Linux kernel with Clang, an alternative compiler for the C language; as of 12 April 2014, the official kernel could almost be compiled by Clang. The project dedicated to this effort is named LLVMLinxu after the LLVM compiler infrastructure upon which Clang is built. LLVMLinux does not aim to fork either the Linux kernel or the LLVM, therefore it is a meta-project composed of patches that are eventually submitted to the upstream projects. -

Automated Installation of Linux Systems Using YaST Dirk Hohndel and Fabian Herschel – SuSE Rhein/Main AG ABSTRACT The paper describes how to allow a customized automated installation of Linux. This is possible via CDRom, network or tape, using a special boot disk that describes the system that should be set up and either standard SuSE Linux CDs, customized install CDs, an appropriately configured installation server, or a tape backup of an existing machine. A control file on the boot disk and additional (optional) control files on the install medium specify which settings should be used and which packages should be installed. This includes settings like language, key table, network setup, hard disk partitioning, packages to install, etc. After giving a quick overview of the syntax and capabilities of this installation method, considerations about how to plan the automated installation at larger sites are presented. -

A Parallel File System for Linux Clusters Authors: Philip H
PVFS: A Parallel File System for Linux Clusters Authors: Philip H. Carns Walter B. Ligon III Robert B. Ross Rajeev Thakur Presented by: Pooja Nilangekar [email protected] Motivation ● Cluster computing is a mainstream method for parallel computing. ● Linux is the most common OS for cluster computing. ● Lack of production-quality performant parallel file system for Linux clusters. ● Linux clusters cannot be used for large I/O-intensive parallel applications. Solution: Parallel Virtual File System (PVFS) for linux clusters. Used at: Argonne National Laboratory, NASA Goddard Space Flight Center, and Oak Ridge National Laboratory. Objectives for PVFS 1. Basic software platform for pursuing further research in parallel I/O and parallel file systems in the context of Linux clusters. a. Requires a stable, full-featured parallel file system to begin with. 2. Meet the need for a parallel file system for Linux clusters. ● High bandwidth for concurrent read/write operations. ● Multiple API support: a native PVFS API, the UNIX/POSIX I/O API, other APIS MPI-IO. ● Common UNIX shell commands, such as ls, cp, and rm. ● Compatible with applications developed with the UNIX I/O API. ● Robust and scalable. ● Easy to install and use. ● Distribute the software as open source. Related Work ● Commercial parallel file systems ○ PFS (Intel Paragon), PIOFS & GPFS (IBM SP), HFS (HP Exemplar), XFS (SGI Origin2000). ○ High performance and functionality desired for I/O-intensive applications. ○ Available only on the specific platforms. ● Distributed file systems ○ NFS, AFS/Coda, InterMezzo, xFS, and GFS. ○ Distributed access to files from multiple client machines. ○ Varying consistency semantics and caching behavior. -

It’s an interesting question, and one that in my opinion has a very simple answer: Package management-or, more specifically, the ability to install and upgrade software over the network in a seamlessly integrated fashion-along with the distributed development model package management enabled.
