        Hi, glusterfs expert
        When I test with
            glusterfs version 3.12.3 I find it quite often that
            sometimes, there are entry remains in gluster volume heal
            <vol-name>info output for long time,
            it does not disappear until you visit it from the mount
              point, is this normal?
