<div dir="ltr"><div>Hello,</div><div><br></div><div>i've finally upgraded our gluster-server to 7.1 (3.8 debian stretch -> gluster-repo 3.12 -> gluster-repo 7.1) and it actually went real smooth. There is just that warning in all brick-logs and every server every 15min i can't really explain myself.</div><div><br></div><div>[2019-12-29 05:51:17.807293] W [socket.c:774:__socket_rwv] 0-tcp.store4-server: readv on <a href="http://192.168.31.60:49077">192.168.31.60:49077</a> failed (no data available)</div><div>[2019-12-29 06:00:47.886369] W [socket.c:774:__socket_rwv] 0-tcp.store4-server: readv on <a href="http://192.168.31.61:49140">192.168.31.61:49140</a> failed (no data available)

</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]. And the best explanation i could find was in a bug report [2], so it seems it's not unusual i just don't like ignoring warnings.</div><div><br></div><div>Anyone here that has similiar warning or could explain what i can do about it?</div><div><br></div><div>Thanks Mika<br></div><div><br></div><div></div><div>[1] <a href="https://lists.gluster.org/pipermail/gluster-users/2015-May/021971.html">https://lists.gluster.org/pipermail/gluster-users/2015-May/021971.html</a></div><div>[2] <a href="https://bugzilla.redhat.com/show_bug.cgi?id=1385525#c3">https://bugzilla.redhat.com/show_bug.cgi?id=1385525#c3</a></div></div>
