The problem is that the ‘glusterd_brick_t’ file context is missing from selinux-policy-targeted 3.14.3-80 on CentOS 8 Stream. It exists in the CentOS 8.4 version: rpm -qpl selinux-policy-targeted-3.14.3-67.el8_4.2.noarch.rpm | grep gluster /usr/share/selinux/targeted/default/active/modules/100/glusterd /usr/share/selinux/targeted/default/active/modules/100/glusterd/cil /usr/share/selinux/targeted/default/active/modules/100/glusterd/lang_ext /var/lib/selinux/targeted/active/modules/100/glusterd /var/lib/selinux/targeted/active/modules/100/glusterd/cil /var/lib/selinux/targeted/active/modules/100/glusterd/hll /var/lib/selinux/targeted/active/modules/100/glusterd/lang_ext Not on CentOS 8 Stream: rpm -qpl selinux-policy-targeted-3.14.3-80.el8.noarch.rpm | grep gluster You can remove the selinux checks from: /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/mount.yml but I’m not sure of the implications of that. This is a show stopper for oVirt and someone from oVirt needs to contact the CentOS 8 Stream maintainers and have them put the selinux context back, or come up with some other workaround.
