[slurm-users] Exclude Slurm packages from the EPEL yum repository

[Philip Kovacs]

 I can assure you it was easier for you to filter slurm from your repos than it was for me to make them available to both epel7 and epel8.
No good deed goes unpunished I guess.    On Saturday, January 23, 2021, 07:03:08 AM EST, Ole Holm Nielsen <ole.h.nielsen at fysik.dtu.dk> wrote:  
 
 We use the EPEL yum repository on our CentOS 7 nodes.  Today EPEL 
surprisingly delivers Slurm 20.11.2 RPMs, and the daily yum updates 
(luckily) fail with some errors:

  You could try using --skip-broken to work around the problem
  You could try running: rpm -Va --nofiles --nodigest


We still run Slurm 20.02 and don't want EPEL to introduce any Slurm 
updates!!  Slurm must be upgraded with some care, see for example
https://wiki.fysik.dtu.dk/niflheim/Slurm_installation#upgrading-slurm

Therefore we must disable EPEL's slurm RPMs permanently.  The fix is to 
add to the file /etc/yum.repos.d/epel.repo an "exclude=slurm*" line like 
the last line in:

[epel]
name=Extra Packages for Enterprise Linux 7 - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch
metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch&infra=$infra&content=$contentdir
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
exclude=slurm*
