LINSTOR controller does not care either.<br></blockquote><div><br></div><div>Thanks for confirming this Robert. </div><div>In my experience, Promox requires a minimum 3 nodes when HA is enabled/required. When HA is enabled, and one of the 2 cluster nodes goes down, then HA will not function properly, due to not enough remaining votes for a working,healthy cluster. </div><div>Since LINSTOR controller functionality in Proxmox is based on HA (VM), that will (indirectly) affect also LINSTOR availability, as the HA VM used to host it, will stop functioning as soon as Proxmox cluster (corosync) looses the quorum majority, hence my recommendation of 3 nodes.<br></div><div><br></div><div>Yannis</div><div><br></div><div> </div></div></div>
