Hello Everyone,
I am using GlusterFS 9.4, and whenever we use the systemctl command to stop the Gluster server, it leaves many Gluster processes running. So, I just want to check how to shut down the Gluster server in a graceful manner.
Is there any specific sequence or trick I need to follow? Currently, I am using the following command:
[root@master2 ~]# systemctl stop glusterd.service [root@master2 ~]# ps aux | grep gluster

For now, We are using
https://github.com/gluster/glusterfs/blob/master/extras/stop-all-gluster-processes.sh to kill all the remaining processes.
Thanks,
