Hi, if you simply reboot or shutdown one of the gluster nodes, there might be a (short or medium) unavailability of the volume on the nodes. To avoid this there's script: /usr/share/glusterfs/scripts/stop-all-gluster-processes.sh (path may be different depending on distribution) If i remember correctly: this notifies the clients that this node is going to be unavailable (please correct me if the details are wrong). If i do reboots of one gluster node, i always call this script and never have seen unavailability issues on the clients. Regards, Hubert Am Mo., 15.

Hi,
the down time is not short or medium in my case, I have followed the
documentation and shared all details as well. couldn't find what can make
the replica volume high available at client, when one of the node is down. I am
not able to access mount point at client until the node is up. if we keep the
node shutdown for 12 hours, gluster volume or mount point at client is not
accessible for same period of time.
Please help on making the gluster volume available at client when one of the
node is not available with replicated volume.
Thanks,
Ahemad

[Gluster-users] Issues with replicated gluster volume
Hi Ahemad, You can simplify it by creating a systemd service that will call the script. It was already mentioned in a previous thread (with example), so you can just use it.
