<p>I do not know how you ended up in this state. This usually
happens when there is a commit failure. To recover from this state
you can change the value of "status" from</p>
<p>the path
/var/lib/glusterd/snaps/<snapname>/<snapuid>/info .
From this file change the status to 0 in nodes where the values
are one. Then restart glusterd on those node where we changed
manually.</p>
<p>Then try to activate it.</p>
