unfortunately no.
but funny thing... today I looked into html source of cluster settings
page (via Firefox's web developer console). Gluster checkbox has this
html code
<input type="checkbox" value="on"
id="ClusterPopupView_enableGlusterService" tabindex="17"
style="vertical-align: top;" disabled="">
when I edited and removed disabled="" part, I was able check that
checkbox. After pressing Ok everything seems to be set but there are
finally three relevant errors in the engine.log
