<br>
I have been testing EL8 + NFS Ganesha 3 (from CentOS Storage SIG) and Gluster v8 (tested both Storage SIG rpms and built from source ) and I have noticed a bug in the SELINUX policy causing the system to fail to boot after the node is fenced until a kernel parameter 'enforcing=0' is passed.<br>
<br>
The reason seems to be the link "/var/lib/nfs" pointing to the shared storage.When the cluster software is stopped gracefully, no issues are observed,as the nfs_setup resource restores /var/lib/nfs .<br>
<br>
Should I open a bug to <a href="http://bugzilla.redhat.com" rel="noreferrer" target="_blank">bugzilla.redhat.com</a> or it's specific to CentOS only ?<br></blockquote><div><br></div><div>Off hand I don't think that's a bug in the nfs-ganesha-selinux package. I've asked the cluster (pacemaker, etc.) devs and the selinux devs what they think. You asked about opening a BZ in <a href="http://bugzilla.redhat.com">bugzilla.redhat.com</a>; but <a href="https://github.com/gluster/glusterfs/issues">https://github.com/gluster/glusterfs/issues</a> is the correct place to report gluster issues.</div><div><br></div><div>For this though I suggest opening an issue in <a href="https://github.com/ClusterLabs/">https://github.com/ClusterLabs/</a> somewhere, maybe <a href="https://github.com/ClusterLabs/fence-agents/issues?">https://github.com/ClusterLabs/fence-agents/issues?</a>?
