rpm-list

Hi,

Some time ago I encountered some problems with the --rpm-list option for
the cobbler repo command. As I understood, the --rpm-list option do not
work with foreign architectures, e.g. if cobbler server is i386 one
cannot make a repo for x86_64.

The related ticket was closed without a explanation why:
https://fedorahosted.org/cobbler/ticket/153

I stumbled over this issue again and it seems to me its even worse. The
repo for the same arch does not work too.

repo with same arch as cobbler server and rpm-list specified:
reposync works but yum complains:

Error: failure: repodata/primary.xml.gz from reponame: [Errno 256] No
more mirrors to try.

I also tried with --mirror-locally turned off, no difference. What are
the use cases for the --rpm-list feature then ? Anyone using this ? As
far as I can see it only produces a partial mirror that is not usable by
yum after mirroring, and thats the best case. In the worse case it is
not even capable to create the mirror.

We use --rpm-list to mirror portions of the EPEL repository. I believe what you are
referring to would be to mirror Satellite/RHN channels from Red Hat. I believe that is
much more difficult and does have some limitations. You might look at the mrepo tool from
Dag Wieers to try and solve that problem, though I don't believe that is perfect,
either.

I want to achieve similar, partial mirrors of repositories like EPEL or
rpmforge but that does not work. On a i386 cobbler server reposync
produces unusable i386 repositories for me. It seems to me that the
createrepo command is not executed (but should). As soon as i do a
manual createrepo the missing file are created and the repository is usable.

Anyway, i will have a look at mrepo.

Can you try again with cobbler 2.0.4?  There have been some
improvements in there that might help you.

This might be because it is going to be a bug with yum that cobbler
can't really fix.  It shouldn't have been closed without comment, but
if yum doesn't support what you are trying to do, there is nothing
that cobbler can do about it.

OK. I was at 2.0.3 from EPEL and now i installed 2.0.4 from EPEL testing
but it did not change anything as far as i can see.

I have do disagree. The --rpm-list feature is announced by cobbler. It
announces a feature that in the end turns out to be unusable (for me at
least). Kind of cheating. The end user is not interested in what tools
are used behind the scenes. The frontend is supposed to do some kind of
error detection and I would expect it to handle cases where it is known
that a specific feature or setting or whatever will be disfunctional.

Or in other words, if the backend tools can not provide the needed
services, cobbler should not pretend it could.

Just some thoughts, no offence please.
