according to $ gluster volume help
volume stop <VOLNAME> [force] - stop volume specified by <VOLNAME>
But even I run this accordingly.
$ gluster volume stop <VOLNAME> force
it still prompted me like
Stopping volume will make its data inaccessible. Do you want to continue? (y/n)
How could we skip this confirmation process?
Check whether this helps:
echo 'y' | gluster volume stop force
