I get messages like this fairly frequently on our SL7 servers: /etc/cron.daily/0yum-daily.cron: Not using downloaded repomd.xml because it is older than what we have: Current : Fri Mar 25 08:54:39 2016 Downloaded: Fri Mar 25 08:54:20 2016 Today, this is from the sl-security repo: -rw-r--r--. 1 root root 3059 Mar 25 08:54 /var/cache/yum/x86_64/7/sl-security/repomd.xml We use a mirroring scheme that is based on time-stamps which may be aggravating this locally, and are mirroring from http://ftp1.scientificlinux.org/linux/scientific However it seems that the time-stamps of these files should never go backwards. Is there something going on in the SL staging process causing this? -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane [log in to unmask] Boulder, CO 80301 http://www.nwra.com
