Hello SL Users,
We have for instance the following situation:
- SL51 host with kernel-2.6.18-53.1.4.el5 (among others)
- kernel-module-openafs-2.6.18-53.1.4.el5 2 1.4.6 73.slp5
is installed but removed recently from the update repo.
- kernel-module-openafs-2.6.18-53.1.4.el5 0 1.4.6 58.SL5
is still in the sl51base repo, but not installed
Now, when I am running "yum update" on a SL51 system with the
kernel kernel-2.6.18-53.1.4.el5 installed, the kernel-module
plugin (package yum-3.0.6-3.sl) tries to install
kernel-module-openafs-2.6.18-53.1.4.el5 0 1.4.6 58.SL5
from the sl51base repo. Eventually, yum fails with the corresponding
message "blabla which is newer is already installed".
Why does the kernel-module plugin
only check what's the newest version of a kernel module
in the repo and sets it to be installed,
regardless if the version installed is newer.
Because we hadn't heard of anyone putting a higher epoch in their
kernel-modules and then taking them out.
The problem is not related to the epoch. It occurs as soon as you install a
kernel module via rpm which is
1) not in any repository (with the version you installed via rpm)
2) but have an older version in some repository.
3) and then run "yum upgrade"
Another possibility to run into the same problem is:
1) We have kernel module foo with version 1.42 in repository A and with
version 0.42 in repository B.
2) We install the kernel module via yum. Version 1.42 will be installed.
3) We remove version 1.42 from repository A - for some reason.
4) We run "yum upgrade". Now the kernel-plugin of yum wants to install version
0.42, but 1.42 is already installed!
You are correct.
The plugin is at /usr/lib/yum-plugins/kernel-module.py
Feel free to fix it.
Troy
p.s. Why in the world do you keep adding and removing all these kernel
modules from your repositories? If you like a kernel module, keep using
it, don't just take it away.
