Dear OSCAR Users & Developers,
after one year of development and just in time for SuperComputing 2006 the new
release of OSCAR is ready! It is downloadable from the sourceforge site.
Many thanks to all who contributed to this version with ideas, requirements,
developments, alpha and beta testing, bug reports and fixes!
The Release Notes for OSCAR 5.0 are attached to this email. You'll notice that
OSCAR 5.0 is significantly different from OSCAR 4.2. You will not be able to
update from OSCAR 4.2 to OSCAR 5.0 because the infrastructure has changed
significantly. Also the way how the first steps of the installation go have
changed, therefore make sure that you read at least the page
http://oscar.openclustergroup.org/oscar_5.0
before you start a new installation.
Happy clustering!
Cheers,
Erich

Known issues:
=============
+ The OSCAR Package Install/Uninstall button from the management panel does
not work. PackageInUn functionality will be added back in the next version.
Until then you'll need to use yume for updating OSCAR packages.
+ After building an image one should remove the yum caches with a command like
# yume --installroot /var/lib/systemimager/IMGNAME clean all
This solves an issue with trying to update live clients with yume.
+ Systemimager fails to recognize the ata_piix module as SCSI module. If your
client nodes are using this module you should create the file
/var/lib/systemimager/images/IMGNAME/etc/systemconfig/hardware.lst
with a line containing the hardware info for the driver. For example:
# ata_piix support for vendorid=0x8086, deviceid=0x2680
8086 2680 scsi ata_piix
