Not sure where to post this.
I think i have found a problem in cobbler reposync.
Sometimes if a rpm is partially downloaded and /usr/bin/reposync is stopped,
say by a collegue rebooting the server, grrr.
/usr/bin/reposync wont continue and throws an error untill the file is
deleted. e.g.
Traceback (most recent call last):
File "/usr/bin/reposync", line 264, in ?
main()
File "/usr/bin/reposync", line 245, in main
path = repo.getPackage(pkg)
File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 652, in
getPackage
cache=cache
File "/usr/lib/yum-plugins/rhnplugin.py", line 299, in _getFile
raise yum.Errors.RepoError, \
yum.Errors.RepoError: failed to retrieve
getPackage/openoffice.org-impress-2.0.4
-5.4.17.1.x86_64.rpm from rhel-x86_64-server-productivity-5
error was [Errno 9] Requested Range Not Satisfiable
cobbler reposync failed
This is not caught by my script because cobbler terminates with a return
code of 0, but cobbler knows it has failed.
Looking at action_reposync.py
rc = sub_process.call(cmd, shell=True)
if rc !=0:
raise CX(_("cobbler reposync failed"))
The return code from /usr/bin/reposync is being caught, but it looks like
what ever handles the exception raised does not pass it on.
Sorry my python is non existant so i cant follow it any further, any one
know how to make a quick fix?

Yes feel free to add it.
I tried the change to use "cobbler list repo" and it works fine.

Nice! Do you mind if I put this in a 'contrib' directory in cobbler's
version control so other people can find it later?
We can mention this on the Wiki too.
One small change I'd make is to make the last awk line run 'cobbler repo
list' instead of grepping the file, that way
it works regardless of the storage backend -- though everyone pretty
much uses the stock one.

Please file bugs in Trac here: https://fedorahosted.org/cobbler, and
I'll take a look at it.
