[SOLVED] yum always updates some metadata ignoring metadata_expire

leniviy · 08-07-2018, 03:18 AM

Hi.
On one of my CentOS 7.5 hosts whenever I launch "yum install" (just to press 'n') it stops for a few seconds after printing "Loading mirror speeds from cached hostfile". tcpdump shows traffic to different mirror sites. For those with port 80 it shows no actual http request, just the tcp handshake.

The metadata_expire setting doesn't affect this, although certain yum messages indeed don't show until it really expires.

"yum -C" doesn't produce this traffic, but I don't want to use it all the time.

I find with RHEL/CentOS7 running "yum makecache fast" helps resolve various issues. It appears the cache is keeping old information that may not have latest repository/mirror information. Often even when I know newer packages are out there "yum list" or "yum install" won't find them until after I've done the above.

Sorry, that haven't changed a thing.

It seems that the fastestmirror plugin ignores its maxhostfileage setting. Deleting /var/cache/yum/x86_64/7/timedhosts.txt helped. Perhaps it's because I added new repos since that file was generated.

You could also try the following command, if you're still having the same issue;

Code:

yum clean all

Yes, "yum clean all" also deletes timedhosts.txt.
