Dear Oscar users,
Here is a description of the minor epic we (a bunch of newbies) went
through so that we could update the modules on our master node on our
Oscar 1.3 Red Hat Linux ver 7.2 PC cluster with up2date. any
comments?
We installed a fresh Redhat 7.2 distribution on the master node and
copied the rpms from the CD onto the tftpboot directory. (We did not
update the master or the tftpboot directory at this point which we
should have done). We downloaded Oscar 1.3 and installed it and got
the 2-clients running successfully. We had to update to the rpm-4.0.4
package on the master node (as described in the manual) manually
(command line) to get the installation to work since the build with
the rpm-4.0.3 package gave errors in the oscar installation which
disguised the real errors we needed to correct. We also had to update
popt to get the new rpm to work. After Oscar 1.3 was installed
correctly, I tried to run up2date and it complained about missing
several specific versions of libraries that were in the rpm-4.0.3
package and it would not run. Presumably these libraries were
overwritten by newer ones in the rpm-4.0.4 installation.
Finally I tried to get the old version of rpm re-installed with the following:
[root@rescluster old_packages]# rpm -q rpm
rpm-4.0.4-7x
[root@rescluster old_packages]# rpm -q popt
popt-1.6.4-7x
[root@rescluster old_packages]# ls
popt-1.6.3-1.03.i386.rpm rpm-4.0.3-1.03.i386.rpm
[root@rescluster old_packages]# rpm -i --force *.rpm
[root@rescluster old_packages]# rpm -q popt
popt-1.6.4-7x
popt-1.6.3-1.03
[root@rescluster old_packages]# rpm -q rpm
rpm-4.0.4-7x
rpm-4.0.3-1.03
[root@rescluster old_packages]# xterm&
So now up2date runs, but when I first tried to update all available
packages I got an error message involving the oscar modules as
follows:
...package dependency problem
Unresolvable chain of dependencies
env-switcher 1.0.4-1oscar requires modules
... (a few other oscar modules) requires modules
pvm-modules-3.4.4+6-2 requires modules >=3.1
After installing the new modules with up2date in groups of 20, I
tracked this error message solely to the
modutils package.
Oscar comes with modules-3.1.6-8oscar which is compatible with
the original redhat 7.2 distribution of modutils-2.4-6-4
but not the upgrade.
so now, I just eliminate the modutils package from the upgrade list
when running up2date.
cheers,
Lance
