Cluster Read Only Mode¶
It is possible to add a cluster with only its hostname and port number, and no username and password credentials. This creates a copy of the cluster and its VMs in your local Ganeti Web Manager database without giving you the ability to change the cluster itself.
In Read-Only mode, you CAN:¶
Assign ownership of VMs to GWM users from the Orphans page
Delete VMs from your Ganeti Webmanager database from the Missing VMs page
Import nodes to your database or delete nodes from it
Assign permissions to users on the cluster or VM (note that although you can assign VM create permission to a user or group, they cannot actually create a VM in read-only mode)
Edit the cluster, so that you can go back and add username/password credentials and gain full privileges on it later.
Delete the record of the cluster from your database (Note: This does not affect the actual cluster)
Record a default quotas for Virtual CPUs, Disk Space, and Memory
Change the cluster’s slug (the name of the cluster as it appears in the url: <hostname>/cluster/<slug>/<vm>)
In Read-Only mode, you can NOT:¶
Redistribute the cluster’s configuration
Start, stop, or reinstall a VM
Migrate or change disks
Access a VM’s console
Create a new VM on the cluster
