Oscar 6.0.1

De mensen van de Open Cluster Group hebben de nieuwe versie 6.0.1 klaargezet van hun verzameling van de beste methodes om een Linux-cluster te realiseren. Open Source Cluster Application Resources, beter bekend als Oscar, ondersteunt verschillende Linux-distributies zoals Debian 4, Ubuntu 8, Fedora Core 9, Red Hat Enterprise Linux 5 en CentOS 5. Voor meer informatie verwijzen we jullie door naar deze pagina. De ontwikkelaars hebben de release van Oscar 6.0.1 met de volgende lijst van veranderingen gepaard laten gaan:

Version 6.0.1:

• Add RPMs for OSCAR core on Fedora Core 9 (both i386 and x86_64).
• Update the RPM list for rhel-5-x86_64 and compatible distributions.
• Merge oscar-base.spec.in and oscar.spec.in.
• Clean up the Makefile portion related to the generation of RPMs for oscar-base.
• Clean up the spec file for oscar-base.
• Update ODA to 1.3.5.
• Update PackMan to 3.1.5.
• Update Yume to 2.8.4.
• Update Selector to 1.0.2.
• During bootstrapping, a log file is now created (/var/log/oscar/bootstrap.log).
• Include two new options to the oscar-config script: debug and verbose.
• During bootstrapping, we install only one core OPKG at a time, to be able to really get details on errors.
• Fix a bug when generating the DHCPD configuration file on Debian.
• New abstraction for the management of system services.
• Include capabilities for file management: download and type detection.
• [Ticket #506] Include a "virtual" OSCAR RPM that allows the installation of all dependencies needed for the OSCAR bootstrap.
• [Ticket #503] Configurator is now a separate component with its own SVN tree, i.e., Configurator is now a prereq.
• [Ticket #507] With prereqs on RPM based system the dumb mode tries to use yum is a package is not locally available.
• [Torque OPKG] Update the list of prereqs for the creation of the binary packages (build.cfg).
• Improve unit tests.
• [Ticket #463] Finish to remove all binary packages from the source tree, oscar-packager provides the needed abstractions for the creation of binary packages.
• Prereqs on RPM systems in dumb mode now try to use yum if a package is not locally available.
• Include the patch from Felipe Zipitria: avoid warnings on some configuration when using OSCAR::ConfigFile.
• Improve the perldoc documentation of different OSCAR Perl modules.
• [Ticket #502] Binary packages for oscar-base do not over-write the /etc/oscar/oscar.conf file anymore.

Version 6.0:

This version provides the latest modifications which will ease future developments. On the roadmap, we already plan to include many project on which students worked during the summer 2008, including a benchmarking framework, a monitoring framework, and mechanisms to deal with specific NFS configuration. This version will also be a good base for bug fixes.

Remember that this version does not provide yet all the capabilities OSCAR were used to provide. For this version, we focused on the implementation of a stable OSCAR core and cleaning up; which should allow us to move forward. More capabilities will be included in future OSCAR-6.x releases.

Right now, OSCAR-6.x supports only RHEL/CentOS 5 for both x86 and x86_64 in a production environment. The support of Debian systems is still experimental since we found a critical bug in opkgc (which should be fixed shortly).

OSCAR-6.0 is available via our YUM/APT on-line repositories. For more details about how to use those repositories, please refer to http://svn.oscar.openclustergroup.org/trac/oscar/wiki/repoTesting. The next version of OSCAR-6.x will be available via the same repositories, providing an easy way to update OSCAR.

• Full support of on-line repositories.
• Implementation of a new bootstrapping mechanism via oscar-config.
• Installation using normal system paths.
• Continue the modularization effort (almost all core components are now in separate packages).
• Improve error handling.
