</div><div><br></div><div>.60 and .61 are two servers with bricks for gluster volume "store4". They are not only the gluster-server, they also are clients that mount the gluster volumes. (replicated gluster volume, that hosts kvm images that run locally on the server)</div><div><br></div><div>Everything really looks good no other errors or warning - just the lines mentioned above. Is this something i should be worried about or can resolve somehow?</div><div><br></div><div>Of course i looked through the web, unfortunately i only really could find one guy that had the same problem but no following messages [1].
