Deleting gluster volume from UI will delete the underlying volume if any of
the hosts in the cluster are online - i.e it's not a database entry
deletion alone, it executes gluster cli command to delete the volume.

Why do you want to delete the volume? Is it to move the hosts to another
cluster/ change compatibility? Which cluster has the gluster volume -
CentOS7 cluster or Default cluster?
