Jessica, Thanks for the detailed info about yum. With your package_method. Cfengine parse the package in this format: Package (apr,1.2.7,x86_64) found Then it try's to see if its installed and matches: > Looking for (apr-1.2.7,*,x86_64) cf3> No installed packages matched (apr-1.2.7,*,x86_64) cf3> -> Looking for (apr-1.2.7,*,x86_64) cf3> No installed packages matched (apr-1.2.7,*,x86_64) cf3> Checking if package (apr-1.2.7,*,x86_64) is at the desired state (installed=0,matched=0) cf3> -> Package promises to refer to itself as "apr-1.2.7-*" to the manager cf3> !! Package name contians '*' -- perhaps a missing attribute (name/version/arch) should be specified cf3> -> Package version seems to match criteria cf3> -> Schedule package for addition This fails because cfengine expect a package name with a seperate version. So it can not find the package 'apr-1.2.7', See out out of cfengine parse the yum output. After this is will schedule the package for update. Because the match/select will always fail. It will always try to install/update the package. A you experienced. Or all combo's of yum must be implemented. I did not know that there where that many ;-). Or you must use package name without versions numbers and use the version in the package_select statement. cf3> -> Package (apr-1.2.7-*,any,any) found cf3> Execute scheduled package addition cf3> Command prefix: /usr/bin/yum -y install cf3> Executing /usr/bin/yum -y install apr-1.2.7-*... cf3> Q:yum -y install apr-1 ...:Loaded plugins: dellsysid, fastestmirror, protectbase, versionlock cf3> Q:yum -y install apr-1 ...:Loading mirror speeds from cached hostfile cf3> Q:yum -y install apr-1 ...: * glite-TORQUE_client: glitesoft.cern.ch cf3> Q:yum -y install apr-1 ...: * glite-TORQUE_externals: glitesoft.cern.ch cf3> Q:yum -y install apr-1 ...: * glite-TORQUE_updates: glitesoft.cern.ch cf3> Q:yum -y install apr-1 ...: * glite-WN: ftp.sara.nl cf3> Q:yum -y install apr-1 ...: * glite-WN_ext: ftp.sara.nl cf3> Q:yum -y install apr-1 ...: * glite-WN_updates: ftp.sara.nl cf3> Q:yum -y install apr-1 ...:10797 packages excluded due to repository protections cf3> Q:yum -y install apr-1 ...:Reading version lock configuration cf3> Q:yum -y install apr-1 ...:Setting up Install Process cf3> Q:yum -y install apr-1 ...:Package apr-1.2.7-11.el5_6.5.x86_64 already installed and latest version cf3> Q:yum -y install apr-1 ...:Package apr-1.2.7-11.el5_6.5.i386 already installed and latest version cf3> Q:yum -y install apr-1 ...:Nothing to do cf3> Q:yum -y install apr-1 ...: cf3> -> Finished command related to promiser "apr-1.2.7" -- succeeded cf3> Package schedule execution ok for apr-1.2.7-* (outcome cannot be promised by cf-agent) regards -- ******************************************************************** * Bas van der Vlies e-mail: b...@sara.nl * * SARA - Academic Computing Services Amsterdam, The Netherlands * ******************************************************************** _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine
