Gluster users - Feb 2024 - Graceful shutdown doesn't stop all Gluster processes

You can comment line 178 and 186 in the script till that option is available.

Okay, I understand. Yes, it would be beneficial to include an option for
skipping the
 client processes. This way, we could utilize the
'stop-all-gluster-processes.sh' script with that option to stop the
gluster server process while retaining the fuse mounts.

No. If the script is used to update the GlusterFS packages in the node, then we
need to stop the client processes as well (Fuse client is `glusterfs` process.
`ps ax | grep
 glusterfs`).



The default behaviour can't be changed, but the script can be enhanced by
adding a new option `--skip-clients` so that it can skip stopping the client
processes.

Hello Everyone,



We are mounting this external Gluster volume (dc.local:/docker_config)
 for docker configuration on one of the Gluster servers. When I ran the
stop-all-gluster-processes.sh script, I wanted to stop all gluster
server-related processes on the server, but not to unmount the external gluster
volume mounted on the server. However,
 running stop-all-gluster-processes.sh unmounted the dc.local:/docker_config
volume from the server.



/dev/mapper/tier1data ? ? ? ? ? ? ? ? ? 6.1T ?4.7T
 ?1.4T ?78% /opt/tier1data/brick

dc.local:/docker_config ?100G ? 81G ? 19G ?82%
 /opt/docker_config



Do you think stop-all-gluster-processes.sh should
 unmount the fuse mount?



Thanks,

Anant

I think the service that shutdowns the bricks on EL systems is something like
this - right now I don't have
 access to my systems to check but you can extract the rpms and see it:

Hi Anant,

why would you need to shutdown a brick to expand it ? This is an online
operation.
