[Gluster-users] Issues with replicated gluster volume

[ahemad shaik]

/usr/share/glusterfs/scripts/stop-all-gluster-processes.sh is to stop the processes ? if one of the gluster node volume goes down with some issues, we didn't do reboot or shutdown, in those cases what we need to do. Will the script/systemd service created from script will be able to notify client that this node going down ? 

can someone please share documentation related to it.
kidnly help.

  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

 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.
