To avoid network bandwidth issues when all our CentOS workstations are updated, we keep a copy of the CentOS repos on Puma in /share. I recently updated the scripts that synchronize the copies repo from CentOS mirrors, choosing one of … Continue reading
We keep most disk space on our server un-allocated and grow partitions as needed. Here’s how: To see how much space is used: root@tempest ~] df -H Filesystem Size Used Avail Use% Mountpoint /dev/mapper/vg_tempest-lv_root 42G 825M 39G 3% / … Continue reading
I wasn’t sure whether a particular file from a yum-managed package had changed. (/etc/sysconfig/httpd as it happens, but that’s not essential to this problem. So, I wanted to (1) download the RPM, and (2) look at the files in it. … Continue reading
