<p class="MsoNormal">We have gluster 3.8.9 setup with 2 nodes, and a number of replicated volumes. We are using Ganesha for HA. This weekend we had to reboot both nodes and seem to have run into an issue. We first attempted to bring them up one at a time but
when only one was up the gluster shared storage wouldn’t start and NFS-Ganesha was running but not setting up the ha (no virtual IPs were being added). Once we had both of them up we were able to get everything back up by doing the following.

<p class="MsoNormal">One concern is, what happens if we have a failure and are only able to bring up one of the nodes? All our clients are pointed at the virtual IP’s so they wont be able to connect without us manually adding them to the interface. Is that
really the way it should work? <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The second thing is just doing a normal reboot. Should we have to disable and enable those services when it comes back up? Do we need to stop certain services before rebooting? Is there something in the setup we may have done wrong?<o:p></o:p></p>
