This behaviour is by design. In a multi node cluster when GlusterD comes up it doesn't start the bricks until it receives the configuration from its one of the friends to ensure that stale information is not been referred. In your case since the other node is down bricks are not started and hence mount fails. As a workaround, we recommend to add a dummy node to the cluster to avoid this issue. > > > > Regards, > > > > Rémi > > > > > _______________________________________________ > Gluster-users mailing list > [email protected]<mailto:[email protected]> > http://www.gluster.org/mailman/listinfo/gluster-users<http://cp.mcafee.com/d/FZsSd6Qm674XLKfc6XCQrELc3AkmhNJ6WbP0V4sUedEThuvupd79EVd79J6XbX3PBTNNKdfz7ol1iQqQVsSJ6JendIeLfIIKfZvxRTDTTeLsKCOUZObbxEVhKqeuEyCJtdmWavaxVZicHs3jq9J4TvAS7DTxPdNP1KVI04hfrFfUY01MjlS67OFek7qUhfrFfUBSWv6xLpOxOHpkDYh7_up1h4jVsSzuVEVjdwLQzh0qmMAuTivNbJQ-d3iWq80LkMnDkQgkDIpCy0yuTivNd41wDY3h1m1VoQglxVEwxl3Ph1axEwrmd418SUedQSaeSv6mJsC>
