Reading Time: 2 minutes After replacing the SAS card on some ESXi 6.5 nodes, I’ve got a strange issue in the vSAN cluster. The vSAN was healthy and apparently working, but when I try to build new VMs wasn’t working at all, saying that there weren’t enough resources. But there was a lot of free reported space. The reason was that single node, the capacity disks where simply “not Healthy”, but reported as mounted.
