Ensuring Cluster Stack Packages Come from LINBIT on RHEL and AlmaLinux

This article will help you ensure that your cluster stack packages and their associated updates come from LINBIT® and not RHEL repositories.

To do this, you will need to exclude certain packages from RHEL or AlmaLinux repositories by editing .repo files in the /etc/yum.repos.d directory.

RHEL 7

/etc/yum.repos.d/redhat.repo:

[rhel-ha-for-rhel-7-server-rpms]
<snip>
exclude=cluster* pacemaker* corosync* resource-agents fence-agents libqb*

[rhel-rs-for-rhel-7-server-rpms]
<snip>
exclude=cluster* pacemaker* corosync* resource-agents fence-agents libqb*

Using subscription manager, which will prevent redhat.repo from being overwritten:

# subscription-manager repo-override \
--add=exclude:pacemaker*,corosync*,cluster*,drbd*,libqb*,resource-agents \
--repo=rhel-7-server-rpms

RHEL 8 and 9

To exclude the necessary packages from enabled RHEL repositories, enter the commands:

# RH_REPOS="`ls /etc/yum.repos.d/*.repo|grep -v linbit`"
# PKGS="cluster\* corosync\* drbd kmod-drbd libqb\* pacemaker\* pcs resource-agents\*"
# for file in $RH_REPOS; do sed -i "/^enabled[ =]*1/a exclude=$PKGS" $file; done

AlmaLinux 8 and 9

To exclude the necessary packages from enabled AlmaLinux repositories, enter the commands:

# AL_REPOS="`ls /etc/yum.repos.d/*.repo|grep -v linbit`"
# PKGS="cluster\* corosync\* drbd kmod-drbd libqb\* pacemaker\* pcs resource-agents\*"
# for file in $AL_REPOS; do sed -i "/^enabled[ =]*1/a exclude=$PKGS" $file; done
