Hi Spacewalkers!
I try to find out what programs and services are providing the package
management functionality on spacewalk. When a package update is
scheduled on the webgui it gets installed on the client (Wolla!). The
yum logs on the client are empty and the the rpm -U does not log
anything by default. Some rhn* logs contain a lot of information but are
had to interpret.
I tried looking at redhat documentation [1] but but could not find a
clear answer. Possible answers could be.
up2date ? (even on when the client OS is Centos ???)
rpm ?
yum ?
rhn_register ?
Could anyone please enlighten me how the package gets updated?
- How the update package is pushed from the server to the client?
- what program/package-manager on the client side client installs the
package?
- Do detailed update logs exist on spacewalk server? I see the client
history logs, the actions scheduled for that client and the result;
i.e., was that action was successful or not. But the information is not
detailed and lacks for example a list of additionally the installed
dependencies. What I would like to see is the list of all packages and
their status, like in YUM log (installed packages, installed
dependencies, deleted packages, failed packages). Do such logs exist
somewhere on spacewalk server or at least on the client?
spacewalk server: Centos6
spacewalk client: Centos6
This leads to one more question requiring some hands on experience with
spacewalk: would you consider spacewalk as a reliable system for package
management (updates) in a Centos5 and Centos6 server environment? I am
basically concerned about rolling back the updates using so called
profile snapshots (That's why I need to know how package gets updated on
the client). Is this feature designed (or safe enough) to be used for
update rollbacks? Is this functionality normally "enough" in real life
scenarios to bring the Server back to "before the update" state.
In other words: would it be reasonable to skip the step doing snapshots
of the virtual-servers before scheduling regular server update with
spacewalk?
