@BHellman said in Let's Test the HA: Disclaimer: I work for LINBIT, makers of DRBD and LINSTOR the tech behind XOSTOR. We can do highly available iscsi targets, we even have guides on our website that take you step by step to do it. These would be outside of XCP-NG, but would serve the same purpose. If there is any interest from Vates to integrate DRBD/HA into XCP-NG, we're always open to discussions. Sounds interesting for pretty much everyone comming from VMware vSAN running SQL Server in a failover-cluster if im allowed to jump the gun

Quick update. I ran this command for each drive on each host... wipefs --all --force /dev/sdX Then tried building the XOSTOR again. This time I got this an error in the XOSTOR page that some random UUID already had XOSTOR on it, but it built the XOSTOR? I have no idea how, or what happened, but it did. So I have my XOSTOR back.
