Thanks. I have set gluster services to start during startup. I believe the self-heal would play the most important role of taking care of the changes in the dead-peer once it comes back up. Any comments or suggestions for the same ?
Thanks & Regards,

I experienced problems shutting down Gluster servers, because the startup scripts (SystemD) did not have dependencies for system shutdown that would stop the Gluster services before anything else. My problems were also related to the fact that my nodes are connected to each other through IPSec links, and during shutdown, the links were cut before the Gluster service was properly shut down. The other node was waiting for the well-known 42 seconds before considering the peer dead, hence not responding to any file request, and hanging all client systems. Not cool.
So the best practice is simply to end the Gluster services before shutting down the server. Everything runs as smooth as it should be, and the clients don't notice any downtime.
Hope this helps.
