I have two CentOS servers: dev and prod. Located at different sites and, as a result, yum on each tends to use different mirrors.
This morning the dev machine alerted me that there were some updates. I dutifully ran "sudo yum update" to get them, noted the kernel upgrade, rebooted and tested. All is well.
Did the same on the production server but it assures me it doesn't need any stinkin' updates. (yet) Apparently the chosen fastest mirror(s) haven't received the updates yet.
Coincidentally, I'll be doing hardware maintenance on that prod server in a few hours. Since I tend to measure his uptime in months, I'd really like to get the kernel update before I shut it down just to have it -- and not have to schedule another reboot in a day.
How do I tell yum to try different mirrors? Is this a function of yum or that "fastestmirror" plugin?
Updated 35 minutes later: Ironically, the prod server just notified me that it now has updates ready. Any suggestions will be tried "next time" this situation arises :-)
