style="font-family: Helvetica-Light;"><b class="" style="font-size: 12px;">Environment:</b></div><ul class="" style="font-family: Helvetica-Light;"><li class=""><span class="" style="font-size: 12px;">Typology: 3 node cluster, replica 2, arbiter 1 (third node is metadata only).</span></li><li class=""><span class="" style="font-size: 12px;">Version: Client and Servers both running 4.1.3, both on CentOS 7, kernel 4.18.x, (Xen) VMs with relatively fast networked SSD storage backing them, XFS.</span></li><li class=""><span class="" style="font-size: 12px;">Client: Native Gluster FUSE client mounting via the kubernetes provider</span></li></ul><div class="" style="font-family: Helvetica-Light;"><span class="" style="font-size: 12px;"><br class=""></span></div><div class="" style="font-family: Helvetica-Light;"><b class="" style="font-size: 12px;">Problem:</b></div><div class="" style="font-family: Helvetica-Light;"><ul class=""><li class=""><span class="" style="font-size: 12px;">Seemingly randomly some clients will be blocked / are unable to write to what should be a highly available gluster volume.</span></li><li class=""><span class="" style="font-size: 12px;">The client gluster logs show it failing to do new file operations across various volumes and all three nodes of the gluster.</span></li><li class=""><span class="" style="font-size: 12px;">The server gluster (or OS) logs do not show any warnings or errors.</span></li><li class=""><span class="" style="font-size: 12px;">The client recovers and is able to write to volumes again after the first node of the gluster cluster is rebooted.</span></li><li class=""><span class="" style="font-size: 12px;">Until the first node of the gluster cluster is rebooted, the client fails to write to the volume that is (or should be) available on the second node (a replica) and third node (an arbiter only node).</span></li></ul></div><div class="" style="font-family: Helvetica-Light;"><span class="" style="font-size: 12px;"><br class=""></span></div><div class="" style="font-family: Helvetica-Light;"><b class="" style="font-size: 12px;">What 'fixes' the issue:</b></div><div class="" style="font-family: Helvetica-Light;"><ul class=""><li class=""><span class="" style="font-size: 12px;">Although the clients (kubernetes hosts) connect to all 3 nodes of the Gluster cluster - restarting the first gluster node always unblocks the IO and allows the client to continue writing.</span></li><li class=""><span class="" style="font-size: 12px;">Stopping and starting the glusterd service on the gluster server is not enough to fix the issue, nor is restarting its networking.</span></li><li class=""><span class="" style="font-size: 12px;">This suggests to me that the volume is unavailable for writing for some reason and restarting the first node in the cluster either clears some sort of TCP sessions between the client-server or between the server-server replication.</span></li></ul></div><div class="" style="font-family: Helvetica-Light;"><span class="" style="font-size: 12px;"><br class=""></span></div><div class="" style="font-family: Helvetica-Light;"><b class="" style="font-size: 12px;">Expected behaviour:</b></div><div class="" style="font-family: Helvetica-Light;"><span class="" style="font-size: 12px;"><br class=""></span></div><div class="" style="font-family: Helvetica-Light;"><ul class="MailOutline"><li class=""><span class="" style="font-size: 12px;">If the first gluster node / server had failed or was blocked from performing operations for some reason (which it doesn't seem it is), I'd expect the clients to access data from the second gluster node and write metadata to the third gluster node as well as it's an arbiter / metadata only node.</span></li><li class=""><span class="" style="font-size: 12px;">If for some reason the a gluster node was not able to serve connections to clients, I'd expect to see errors in the volume, glusterd or brick log files (there are none on the first gluster node).</span></li><li class=""><span class="" style="font-size: 12px;">If the first gluster node was for some reason blocking IO on a volume, I'd expect that node either to show as unhealthy or unavailable in the gluster peer status or gluster volume status.</span></li></ul></div><div class=""
