NFS-Server with CentOS 8 / Red Hat 8 for VMware vCenter Backups

In various community meetings, we often talk about backups for VMware vCenter. As you know, image based backups are only conditionally “supported”. It can go well, but in most cases the VMware vCenter will not be fully restored and you will be forced to re-deploy the appliance. Community and customers are ambivalent, one backs up his VMware vCenter via Veeam etc., the other via the […]

Unable to delete an “inaccessible” datastore (Zombie datastore)

I built a new storage array and migrated the VMs accordingly. But the server gave the following error message: I noticed that the old datastore is still shown as “inaccessible” in vCenter: And even via esxcli I don’t see the datastore anymore: So I first choose the classic way, putting the Server in Maintenance Mode and “Reboot does Good”.
