Hi ahemad, the script kills all gluster processes, so the clients won't wait for the timeout before switching to another node in the TSP. In CentOS/RHEL, there is a systemd service called 'glusterfsd.service' that is taking care on shutdown to kill all processes, so clients won't hung. systemctl cat glusterfsd.service --no-pager # /usr/lib/systemd/system/glusterfsd.service [Unit] Description=GlusterFS brick processes (stopping only) After=network.target glusterd.service [Service] Type=oneshot # glusterd starts the glusterfsd processed on-demand # /bin/true will mark this service as started, RemainAfterExit keeps it active ExecStart=/bin/true RemainAfterExit=yes # if there are no glusterfsd processes, a stop/reload should not give an error ExecStop=/bin/sh -c "/bin/killall --wait glusterfsd || /bin/true" ExecReload=/bin/sh -c "/bin/killall -HUP glusterfsd || /bin/true" [Install] WantedBy=multi-user.target Best Regards, Strahil Nikolov На 16 юни 2020 г. 18:41:59 GMT+03:00, ahemad shaik <ahemad_shaik@xxxxxxxxx> написа: > Hi, >I see there is a script file in below mentioned path in all nodes using >which gluster volume >created./usr/share/glusterfs/scripts/stop-all-gluster-processes.sh >I need to create a system service and when ever there is some server >down, we need to call this script or we need to have it run always it >will take care when some node is down to make sure that client will not >have any issues in accessing mount point ? >can you please share any documentation on how to use this.That will be >great help. >Thanks,Ahemad > > > > >On Tuesday, 16 June, 2020, 08:59:31 pm IST, Strahil Nikolov ><hunter86_bg@xxxxxxxxx> wrote: > > 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. > >Best Regards, >Strahil Nikolov > >На 16 юни 2020 г. 16:02:07 GMT+03:00, Hu Bert <revirii@xxxxxxxxxxxxxx> >написа: >>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.
