[Gluster-users] Graceful shutdown doesn't stop all Gluster processes

Fri Feb 16 16:48:20 UTC 2024

Hi Strahil,

Yes, we mount the fuse to the physical host and then use bind mount to provide access to the container.

The same physical host also runs the gluster server. Therefore, when we stop gluster using 'stop-all-gluster-processes.sh' on the physical host, it kills the fuse mount and impacts containers accessing this volume via bind.

Thanks,
Anant

Hi Anant,

Do you use the fuse client in the container ?
Wouldn't it be more reasonable to mount the fuse and then use bind mount to provide access to the container ?

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:
