Description

This is caused by the "private" mirror flag.. DL failures increment the mirror's failure counter, halving speed estimate each time. Normally, Yum would avoid this mirror after few failures, but the "private" flag overrides speed estimate, and there's just one private mirror, so urlgrabber still considers this one the best.. But for any given request, when the "private" mirror fails, it should be masked, and other (non-private) mirrors should be tried in turn.. is this the case? The log suggests that ONLY one mirror is ever tried.. Re the bug: We want to prefer private mirrors, but probably only when there are no recent failures. If the mirror failed last time, ignore the private flag, and use ordinary speed estimation.. do you think that could work? (In reply to comment #1) > This is caused by the "private" mirror flag..

The log suggests that ONLY one mirror is ever tried.. Yeah, I have noticed later that the files are not actually downloaded and only zero sized "files" are stored in the yum cache. What's interesting is that metadata from a non-private mirror are downloaded, but the packages are not. I will check if the next mirror is broken. > Re the bug: We want to prefer private mirrors, but probably only when there > are no recent failures.

I think it works so in F-16 (guests on the same s390 machine I was trying here) - when the first (private) mirror fails, then all subsequent downlads are switched to next mirror. python-urlgrabber-3.9.1-21.fc18 has been submitted as an update for Fedora 18. https://admin.fedoraproject.org/updates/python-urlgrabber-3.9.1-21.fc18 Package python-urlgrabber-3.9.1-21.fc18: * should fix your issue, * was pushed to the Fedora 18 testing repository, * should be available at your local mirror within two days.
