Yeah, that's a discussion we had just after the last kernel update push : 2.8Gb were pushed (kernel/kernel-firmware/kernel-docs,etc) all being each time drpm'ized. We noticed that by the fact that several mirrors (slow mirrors) were still rsync'ing after several hours :-( > > Is it possible to move the drpms directories to special mirrors > only.

Well, Johnny modified the numbers of deltarpms created now (so up to 5 drpms per package now) so the total size occupied by those drpms should be less than before (was verified yesterday, with last rsync between mirrors deleting quite some files) Problem is that we can't move those drpms to another specific server, as they are declared in the repodata on each mirror : it's a matter of "is yum-presto installed and enabled" that will trigger the use of those drpms (or not). > > Sorry, I don't have detailed numbers anymore, I've just disabled to > mirror the drpms subdir for now. (All numbers above are from memory, > my local mirror doesn't have drpms anymore.) And you'll not have errors if yum-presto ins't installed/enabled. Even if it is, it will try to fetch the drpms and will fail to find them so it will go with the normal packages (iirc) > > Keeping the official CentOS mirror rather small should be a real > plus for the large volume of mirror sites and the real good > distribution of CentOS. > > Thanks a lot for CentOS, > > Florian La Roche > -- Fabian Arrotin gpg key: 56BEC54E | twitter: @arrfab
