<div dir="auto">Hello,</div><div dir="auto"><br></div><div dir="auto">Quick question, just wondering how will "auto-evict" affect a 3 node linstor cluster with a replica number of 2? Say that node1 goes down for more than an 1h, linstor will try to replace its drbd resources to either node2 or node3 assuming that the redundacy level falls below 2 and there's enough free space in the backing device on remaining nodes (will diskless clients count in this case?).</div><div dir="auto"><br></div><div dir="auto">How will linstor respond in the case where node1 comes back online? Will it just restore back drbd resources on it ? or it will just reject that node from being a part of the cluster and in this case the node will have to be rejoined to the cluster.</div><div dir="auto"><br></div><div dir="auto">Thank you,</div><div dir="auto">Yannis</div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, 9 Nov 2020 at 11:16, Rene Peinthor <<a href="mailto:rene.peinthor@linbit.com">rene.peinthor@linbit.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)"><div dir="ltr">Hi!<div><br></div><div>This release brings 2 new added features, auto-evict and configurable ETCD prefixes:</div><div><br></div><div>Auto-Evict:</div><div>If a satellite has no connection to the controller for more than an hour, the controller will mark that node as EVICTED and remove all its DRBD-resources.
