Scaling out vSAN cluster Compute, File Service Shares and iSCSI Target Service.
Hello Everyone, Today, we are going to cover up how to scale out the vSAN cluster compute, Storage, File Service Shares and iSCSI Target service. In my case, I have a cluster of 4 hosts running on vSphere 7 and vSAN 7 and I want to add a new host ( ESXi05 ) to my existing vSAN cluster, expand the vSAN Data store and also expand my vSAN File Services cluster. Before going forward on this, we need to make sure that this new ESX host has same configuration like the existing ones in terms of CPU, RAM, Network and Disk. First of all, when you add a host into the cluster you need to make sure that it should be in maintenance mode. If it is not in maintenance mode then vSAN FS will instantly try to clone a vSAN File Services agent VM (FS VM) on it and that process will fail as there’s no disk group yet. After you added it to the cluster, you have to create the disk group first. Claim all the disks that need to be part of the disk group and create the disk group. When you have d
